Why all of a sudden do you feel like it is 3 x harder to walk up a hill or a stairwell, or why has your iron levels dropped?

Blood volume increases significantly within the first few weeks of gestation and increases progressively throughout the pregnancy. The total blood volume increase varies from 20% to 100% above pre-pregnancy levels, usually close to 45% of average woman. 

"A healthy woman bearing a normal sized foetus, with an average birth weight of about 3.3 kg, will increase her plasma volume by an average of about 1250 ml, a little under 50% of the average non-pregnant volume for white European women of about 2600 ml. There is little increase during the first trimester, followed by a progressive rise to a maximum at about 34-36 weeks, after which little or no further increase occurs." (National Library of Medicine) A non-pregnant woman has about 100ml of blood per minute flowing through the uterine artery, but in early pregnancy this increases to about 120 ml per minute. Once a woman is close to her due date, the blood flow has increased to about 350 ml per minute.

Interestingly enough the research shows that physically active women possess significantly greater vascular volumes than their sedentary counterparts.

WHY DO WE GET AN INCREASE

Pregnancy requires dramatic changes in blood flow, the most obvious being that which occurs in the uterus and the development of the placenta to make a baby grow.

WHAT OTHER THINGS HAPPEN AS A RESULT OF THIS INCREASE?

• Blood flow to the skin increases, making a newly pregnant woman feel warmer and perhaps sweat more, particularly from her hands and feet.

• The increase boosts the body metabolism by about 20%, creating more body heat and making pregnant women less likely to feel the cold the body temperature will often rise to about 37.8 C degrees. (Normally 37)

We have all heard of a placenta but many have never heard about the condition PLACENTA PREVIA. It may sound like a horrible breakfast cereal but to those pregnancies which it affects its an awful reality.

It occurs when a baby's placenta partially or totally covers the mother's cervix — the outlet for the uterus. Placenta previa can cause severe bleeding during pregnancy and delivery. If you have placenta previa, you might bleed throughout your pregnancy and during your delivery. With it afffecting approximately 0.5% of pregnancies, it is the most common cause of bleeding in the third trimester.

So you may ask why is this a problem in a pregnancy? Well as the cervix thins and dialates- (getting ready for labour) and the placenta is attached the blood vessels tear and result in bleeding. The lower uterus is less able to contract and restrict (stop) the bleeding in this area resulting in uncontrolled bleeding.

The advanced age of a mother, a smoker or multiple babies are the main risk factors for this to occur. But also a woman who has had multiple pregnancies, a previous previa, previous uterine or cervical surgery or a cocaine user.

With Placenta Previa there are three catergories: marginal, partial or complete. Most diagnosed in the second trimester resolve themselves especially if they are not major. (84% complete and 98% of marginal will have resolved by 28 weeks).

Most woman diagnosed with this will endure an ultrasound with some getting put on bed rest ,for extreme cases, or Pelvic Rest (NO hanky panky). The biggest risk comes from the onset of labour. Many with moderate to severe previa will have to undergo a routine cesarean also if there is blood loss, foetal distress or evidence for preterm labour. 

So Placenta Previa is no walk in the park and there is no direct correlation between anything in particular-some pregnancies it just happens even if you didn't have it previously.

SUMMER for many is their favourite season of the year...until they get PREGNANT and then it becomes uncomfortable!!! There are a few things to take note of as you brave the heat this summer.

PREGNANCY

It's not just that it's hotter outside, but pregnant women are hotter too: In the first trimester, the progesterone hormone increases body temperature. Pregnant woman's body temperature is already higher than normal so add in scorching summer temperatures and if you are not careful dehydration or other medical problems could arise.

Dehydration is common in the summer months. Did you also know pregnant woman is more prone to sunburn than non-pregnant woman? Other not so nice side effects of the summer heat is swelling, chaffing, 

Surviving the summer heat is necessary if you are pregnant and here are some tips:

1. Avoid direct sunlight.

Do outside activity early in the morning or after the sun sets. 

2. Stay hydrated.

Water intake should about eight to 10 glasses per day and should be more if you are exercising. Drink low-sugar electrolyte fluids, especially if you’re going to spend time outside. 

3. Dress for the heat.

Wear loose, breathable clothing and a hat to reduce sun exposure. 

4. Spritz water often.

Carry a spray bottle with you and spritz yourself with water to cool down your body temperature. 

5. Be smart about exercise.

Swimming is a terrific way to exercise and keep your body cool. Or stay inside and work out at the gym or walk laps at the mall. 

6. Wear sunscreen.

Be sure to reapply after sweating or swimming. Choose a brand with at least SPF 30 and make sure your face is protected. 

BREASTFEEDING

Newborn babies need extra care and attention when it becomes hot. Quite often they will want to breastfeed more reguarly, though become agitated due to the sweaty nature of skin to skin so might feed more less time.  

The Australian Breastfeeding Association reports the following:

"Most parents worry at some stage that their fully-breastfed baby may not be getting enough to drink in hot weather and they ask if they should give boiled water or fruit juice 'just in case'. The answer in most cases is that extra fluids are not required if your baby is breastfed whenever he needs and this may be more often than usual - just as you are drinking more often.

Breastmilk contains a perfectly balanced ratio of food and water to meet all your baby's needs. It is a living fluid, ever-changing to suit your baby and even in response to the weather! The first milk your baby gets from a full breast has a low fat content and naturally quenches baby's thirst. Once the let-down has occurred, the fat content of the milk gradually increases as the breast softens. This later milk has a creamier appearance and satisfies baby's hunger. 

In hot weather a thirsty baby may want to breastfeed more frequently but for shorter periods. In this way he is getting more low-fat milk and so is satisfying his thirst. If you need to be away from your baby, it is preferable that he has your expressed breastmilk (EBM).

An older baby or toddler who is no longer exclusively breastfed may be encouraged to drink water between breastfeeds. You can also offer extra 'snack' breastfeeds to keep him well hydrated. Another refreshing idea for toddlers is to freeze fruit pieces, such as orange quarters, peeled banana or slices of pineapple - cooling and fun, just be prepared for the very sticky mess!

• Some babies become sleepy travelling in hot weather. You may need to stop and wake your baby for feeds.
• The effect of car airconditioners can cause some dehydration - so extra breastfeeds may be necessary on long trips, even if you are cool.
• Prams that are enclosed are airless and can get very hot. An open-weave bassinette, cradle, layback stroller, baby hammock, cot or portable cot is probably cooler for your baby to sleep in."

As a result of Mum needing to feed more often and the heat making her dehydrated she needs to increase her water quantity. Signs of dehydration include irritability, headache, dry mouth, a feeling of thirst, and darker-than-usual urine. Prevent dehydration by carrying a refillable water bottle with you. It is suggested  drinking a glass of water every time baby drinks. If water’s not really your thing, eat more high-water-content fruit, like watermelon, as well as frozen fruit and other fresh fruits and vegetables.

Outfits should also be loose, comfortable and made from a performance/breathable fabric. You may also want to carry a bamboo/cotton sheet to place between yourself and the baby during a feed. Our new cotton breastfeeding tshirt is a great idea as the zip allows for easy discrete access and there is material that remains between you and bub.

Stay vigilant and HYDRATED this Summer!

For some this is true: Don't drink the water you'll get pregnant! For a growing number the ability to fall pregnant is a long and ardious process with many roller coaster rides of emotions and pregnancy test kits. The angst felt by woman who see their friends/relatives/work mates fall pregnant within a drop of a hat is indescribable. They keep saying to themselves: 'When will it be my turn?'

Just because you haven't conceived doesn't mean you cant or wont be able to fall pregnant naturally- sure there are some medical reasons that might inhibit it but one thing is for certain you need to put your body in the best healthy state possible.

Did you know: 

~Around four per cent of all children born in Australia are the result of IVF -- that's the equivalent one child in every average sized classroom.

~The success rates of IVF significantly drops from 35 per cent in patients under 30 years old to just eight per cent for women over 40 years of age.

~A quarter of Australian women undergoing IVF are over the age of 40.

This leaves many to ask how can I place my body in the best possible space to fall pregnant?

We have compiled some tips, foods and ideas to help you on your way:

1. Healthy weight

Being overweight or underweight can affect your chances of conceiving. Too much or too little body fat can make you have irregular periods or stop them completely, which can affect your ability to conceive.

+Your weight is healthy if your body mass index is between 20 and 25.

+Women whose BMI is more than 30 or under 19 may have problems conceiving.

+If your partner's BMI is more than 30, his fertility is likely to be lower than normal.

     2. Exercise

Studies of the effects of exercise on fertility have found that vigorous exercise reduces the risk of ovulation problems and that moderate exercise decreases the risk of miscarriage and increases the chance of having a baby among women who undergo ART(Assisted Reproductive Technology.

Polycystic ovary syndrome (PCOS) is a complex condition which is associated with infertility. Women with PCOS often have irregular or no periods because they rarely ovulate. For overweight and obese women with PCOS regular exercise can increase the frequency of ovulation which leads to more regular menstrual cycles. As ovulation becomes more frequent, the chance of conceiving increases. While studies show that exercise boosts female fertility it is important to note that a large amount of very high intensity exercise may actually reduce fertility and the chance of having a baby with ART. So, it’s a good idea to avoid very high intensity exercise while trying for a baby.

There is also a link between smoking and poorer quality sperm, although the effect on male fertility isn't certain. But stopping smoking will improve your partner's general health.

There's no clear evidence of a link between caffeine, which is found in drinks such as coffee, tea and cola, and fertility problems. Though it is recommended to keep the caffeine at a lower level. There is also some prescription drugs and illicit substances that will interfere with the ability to fall pregnant.

     4. Food

+Following a low-carb diet may improve hormone levels associated with fertility, especially among women with PCOS.

+To boost fertility levels, avoid foods high in trans fats. Eat foods rich in healthy fats instead, such as extra virgin olive oil.

+Some studies suggest that eating more calories at breakfast and less at your evening meal can improve fertility.

+Taking an antioxidant supplement or eating antioxidant-rich foods can improve fertility rates, especially among men with infertility.

+Eating a diet high in refined carbs can raise insulin levels, which may increase the risk of infertility and make it harder to get pregnant.

+Eating more protein from vegetable sources, instead of animal sources, may improve fertility levels in women.

+Replacing low-fat dairy products with high-fat versions may help improve fertility and increase your chances of getting pregnant.

+Consuming iron supplements and non-heme iron from plant-based food sources may decrease the risk of ovulatory infertility.

    5. Relax

The last piece of the puzzle that we are sharing is the impact that the stress or worry will have on conception. We know of several examples of woman who were so stressed/anxious/uptight about the whole process and when they gave up and stopped trying so hard- guess what they FELL PREGNANT!

As your stress levels increase, your chances of getting pregnant decrease. This is likely due to the hormonal changes that occur when you feel stressed. Having a stressful job and working long hours can also increase the time it takes you to become pregnant.

In fact, stress, anxiety and depression affect around 30% of women who attend fertility clinics.

Receiving support and counselling may reduce anxiety and depression levels, therefore increasing your chances of becoming pregnant.

Our next article on fertility is going to be on the small percent of woman who conceive fine in the first pregnancy and then struggle with their second (second infertility). This actually accounts for a whopping 50% of infertility cases.

The above information has been collated from a range of sources and research papers.

A new study finds even moderate exercise during pregnancy increases a compound in breast milk that reduces a baby's lifelong risks of serious health issues such as diabetes, obesity and heart disease.

A new study led by researchers at The Ohio State University Wexner Medical Center and College of Medicine finds even moderate exercise during pregnancy increases a compound in breast milk that reduces a baby's lifelong risks of serious health issues such as diabetes, obesity and heart disease.

They already know that exercising during pregnancy is beneficial to the unborn baby but they wanted to also understand the WHY. When they did their original study they found that the health benefits from fit mums transferred to the pups, proving that they were, in fact, passed through breast milk and not simply inherited genetic traits.

Researchers followed about 150 pregnant and postpartum women using activity trackers and found that those who had more steps per day had an increased amount of a compound known as 3SL in their breast milk, which they believe is responsible for these health benefits.

They are now trying to see if they can extract this 3SL so that maybe they can add it to baby formula to help Mums who were maybe on bed rest or can’t breastfeed.

Dorothy M. Davis states: “Exercise is also great for your overall health during and after pregnancy, so anything you can do to get moving is going to benefit both you and your baby."

So there you have it even more reason to get out and get moving with your bump on board!

The sense of smell is very important. Did you know that this sense often gets affected due to depression? Many observe during pregnancy that their sense of smell heightens often making nausea worse so why is it that many suffer a loss of smell in the postanatal stage due to postnatal depression or other mental illness post baby?

"Personally, my husband did not believe me that my sense of smell had gotten so bad due to my postnatal depression and anxiety. Unfortunately now many smells go unnoticed or the degree of the smell needs to be greater in order to sense it..."

So here is why?

Depression, schizophrenia and seasonal affective disorder all suppress the sense of smell. The olfactory bulbs is the part of the brain that gives us our sense of smell. Researchers have found that the more severely depressed a person was, the smaller their olfactory bulb.  Therefore this suggests that depression may cloud, but not damage, a person's sense of smell. The reduced brain response to odours found in depressed persons may be tied to problems in two closely connected parts of the brain that play an important role in processing emotional information and smell, known as the orbitofrontal cortex and amygdala.

The effects were present whether or not an individual was taking antidepressant drugs.

It has also been noted that once the depression has been successfully treated the sense of smell/response to smells returned back to their normal levels.

Many pregnant Mums are facing the news that their antenatal classes have been cancelled at their delivery hospital. If you are a first time Mum or a Mum with a large gap in between these classes offer a great base. They give pregnant Mums an information bank on what to expect in delivery, options for birth, bathing, sleeping, changing nappies and a whole heap of practical tips and tricks when navigating the birth, delivery and early few days.

Many hospitals and birthing rooms have had to cancel these for the near future due to CON-VID19. Not having this access can increase the anxiety, fear etc for the expecting Mum.

We have done a bit of a run around and here are some paid/unpaid courses that we have found:

The world has gone into a panic over the Caronavirus- there is NO toilet paper on supermarket shelves, people are panic buying their staples and don’t even mention HAND SANTISER...

So should pregnant woman be worried?

Pregnant women tend to have more serious flu infections than people the same age who aren't pregnant, according to the Centers for Disease Control and Prevention. That’s because pregnancy changes the immune system somewhat and lung capacity decreases as a woman’s pregnancy progresses. Though this doesn’t mean that pregnant women will experience coronavirus more severely. There are just not enough studies on pregnant women and coronavirus for experts to say.

“There were some reports of women who are pregnant that have been published, but they're very small numbers,” Adalja said.

Basically what this means is that pregnant women are as at risk for coronavirus as any one else whose immune system is currently compromised and should take precautions as such.

While this might sound worrisome, the experts recommend that pregnant women follow the same smart behaviors that everyone should practice.

“This is a virus that doesn’t have a vaccine or any kind of treatment so the best protection is really just common sense hygiene that you would use during flu season anyway,” Adalja said.

Wash your hands, avoid sick people

This means frequent and proper hand washing. Pregnant women (and all people) should use soap and warm water and rub their hands — including their palms, wrists and between fingers — together vigorously for 20 seconds or about the length of “Happy Birthday.”

“Wash your hands, avoid sick individuals, if you are sick cover your cough,” Adalja said.

While influenza is a different virus than coronavirus, pregnant women should get a flu shot if they have not already received one. It will protect them from getting the flu, which can be more serious in pregnant women. And, fewer flu infections means that doctors can focus their resources and energy on helping patients with coronavirus.

“The more people that are vaccinated against influenza, the less of a burden we're going to have in our hospitals,” Adalja said. “We need to have room to take care of patients that may have the novel coronavirus.”

Do you need a mask if you're pregnant? Nope

Pregnant women do not need to buy masks to protect themselves. Only N95 respirators are effective and a mask prevents you from spreading coronavirus.

"If you put a mask on if you’re sick, that prevents you from spreading the germs to other people,” Dan McGee a pediatric specialist at Helen DeVos Children's Hospital in Grand Rapids, Michigan, told TODAY Parents. “But to go out in public wearing a mask, especially the flimsy lightweight surgical mask you see people wearing, it's not going to prevent the virus from coming in contact with you.”

There is still little known about the virus and how it effects each age and individual. 

So the news is a mask isn’t going to protect you- increasing your personal hygiene standards will!

1 in 5 pregnant woman develop some degree of pelvic girdle pain. It doesn’t have an impact on the unborn baby but Mum to be struggles with pain and movement.

PGP in pregnancy is a collection of uncomfortable symptoms caused by a misalignment or stiffness of your pelvic joints at either the back or front of your pelvis. PGP is not harmful to your baby, but it can cause severe pain around your pelvic area and make it difficult for you to get around. Different women have different symptoms, and in some women PGP is worse than in others. Symptoms can include:

• pain over the pubic bone at the front in the centre
• pain across one or both sides of your lower back
• pain in the area between your vagina and anus (perineum)

Who is more at risk of developing this painful condition in pregnancy?

Factors that may make a woman more likely to develop PGP include:

• a history of lower back or pelvic girdle pain
• previous injury to the pelvis, for example from a fall or accident
• having PGP in a previous pregnancy
• a physically demanding job
• increased body mass index
• emotional distress and smoking

So what can be done?? Treatments for pelvic pain in pregnancy...

The earlier invention happens the better it is.

• Be as active as possible within your pain limits, and avoid activities that make the pain worse.
• Rest when you can.
• Get help with household chores from your partner, family and friends.
• Wear flat, supportive shoes.
• Sit down to get dressed — for example don’t stand on one leg when putting on jeans.
• Keep your knees together when getting in and out of the car — a plastic bag on the seat can help you swivel.
• Sleep in a comfortable position, for example on your side with a pillow between your legs.
• Try different ways of turning over in bed, for example turning over with your knees together and squeezing your buttocks.
• Take the stairs one at a time, or go upstairs backwards or on your bottom.
• If you’re using crutches, have a small backpack to carry things in.
• Use an ice pack (gel pack, frozen peas, wrapped in a pillow slip) over the pelvic joints (front and back ‘dimples’) to reduce pelvic joint pain and inflammation. Use for 10 to 15 minutes only, several times a day.
• If you want to have sex, consider different positions such as kneeling on all fours.

You should also avoid:

• standing on one leg
• bending and twisting to lift, or carrying a baby on one hip
• crossing your legs
• sitting on the floor, or sitting twisted
• sitting or standing for long periods
• lifting heavy weights, such as shopping bags, wet washing or a toddler
• vacuuming
• pushing heavy objects, such as a supermarket trolley
• carrying anything in only one hand (try using a small backpack)

Physiotherapy aims to relieve or ease pain, improve muscle function and improve your pelvic joint position and stability, and may include:

• manual therapy to make sure the joints of your pelvis, hip and spine move normally
• exercises to strengthen your pelvic floor, stomach, back and hip muscles
• exercises in water
• advice and suggestions including positions for labour and birth, looking after your baby, and positions for sex
• Pain relief, such as TENS
• equipment if necessary, such as crutches or pelvic band.

Nadine is a Brisbane Mum of two, a personal trainer, Emergency Military Nurse, blogger and a health and fitness enthusiast. Nadine has lived and breathed fitness for many years and was motivating the troops at F45 until she went on maternity leave.

During both pregnancies Nadine suffered from severe HG (Hyperemesis Gravidarum) or extreme morning sickness where she had to be hospitalised a number of times due to dehydration/monitoring. For those of you who know Nadine would appreciate that she gives everything 110% and will train anywhere/anytime. Due to unforeseen circumstances Nadine went into labour 6 weeks early and underwent an emergency caesarian. She then spent the next few weeks going back and forth to the special care nursery-pumping around the clock to nourish her little one.

For Nadine, exercise is like brushing her teeth, it is part of her day so when she made the conscious decision to NOT return to exercise postpartum it was a big thing. Listening to her inner dialogue and body is an important message for all Mums. Some tend to rush back into a regime which they may not be ready for mentally or physically- the fourth trimester is just as important as the first three…

“As you guys know I made the very conscious decision to NOT return to ‘Training’ at 6 weeks when I was cleared to begin ‘light’ exercise. Hear me out tho!! It’s interesting seeing me talk about my birth because birth trauma is REAL and what we experienced to bring Beckham here safely was incredibly scary for all involved but that is a story for another day perhaps, this is something I deal with everyday…. Anyhow this isn’t just about my birth experience….because….I hadn’t felt ready and I had to listen to that internal dialogue. I knew my recovery was going to be longer in duration due to what occurred physically and mentally for me and I know that i have had to be very meticulous, careful and very structured and progressive with my recovery. Slow and steady is absolutely what is needed for me and my body. Physically and mentally my mind and body have been through the wars. And my body has needed REST and a chance to do some internal repair on its own.-mind, body and soul without the additional stressors….Irrespective of my birth experience, I also DECIDED that the 4th trimester was something again that I wanted to immerse into, to truly soak in the time with my newborn and my family…time I’ll never get back, time to bond, time to find our groove. And without the added pressure or ‘postpartum bounce back’ that seems to be on the trend which I refuse to enter into….

Project ‘get my body back’, and some rapid postpartum mum bod has been so far out of my priorities it is not funny. That may seem interesting for someone whose life is revolved so heavily around health and fitness…(if your new to my page you may not know that I have a background in personal training, group coaching, have my online coaching and mentoring business, published fitness modelling and heavily involved in this industry) BUT  and that’s not to say others that return sooner are doing the wrong thing, I would hope we are all guided by the professional advice and pave our own path unique to our journey, but what I am saying is this is MY journey and my decision making and  SLOW RETURN is and has been my PRIORITY.

But THIS to me is HEALTH! Its looking after ME in all life pillars- the physical sense, the emotional sense etc etc. I have had times where I’ve wanted to get back into it. Let’s not lie. BUT it was in those moments I reminded myself of THIS. Newborn life is fleeting and Ive focused my time and energy into my baby, my family and my WELLBEING OVERALL and gentle walks with Beckham a couple of days a week and that is it, focusing on nutrition especially when a prep baby is exclusively breastfed and that is my HEALTH, my body right now is still an extension to someone else aka BABY BECKS and will be for a while. These decisions have been easy to make-especially when it involves a MIRACLE baby that was born prematurely after a traumatic birth and him being in hospital in special care for the first few weeks of his life and heck a whirlwind pregnancy with trials along the way from the get-go, trust me when I say that we were a bees dick away from our birth being the catastrophic WORST day of our lives with the outcome being potentially VERY different…now as a result; my core and abdominals have needed and will be needing progressive rehab work just like anyone would need to; but perhaps on a grander scale due to what occurred that day. Which i too have been and will continue to be working on. My c-section fortunately and unfortunately had to be rapid, had to be severe, had to be rough and was complicated to say the VERY least. What happened had to happen in order to BRING our baby out alive.

Someone doesn’t recover from birth trauma overnight. Im a resiliant  person but Im not immune from that- it rocked me and Dane too- because our birthing partners experience it too lets not forget them. And it still does. It takes time. And I work on that in various ways everyday. We are appreciative and grateful with what eventuated in the end but it was a harrowing experience that perhaps I’ll share one day.

In a nutshell, taking this time slow but smart, meticulous and planned, progressive in nature and ensuring reassessment on all fonts along the way, but more importantly being discerning of where I focus my time and energy while I recover has been my priority.  I know where my body ‘can go’, what it ‘can’ look like, what it is ‘capable’ of doing and achieving. But doing that in record time would be foolish and detrimental long term. Pregnancy and birth is short term, my postpartum is FOREVER. AND I choose to honour and look after that!!!!!

I’m 4 months postpartum this weekend. I now move into a new phase of my rehab. Take note, in my opinion I started rehab day 1- it just looks different which is MY VARIATION OF NORMAL. And being in a ‘gym’ hasn’t been part of it until now. 4 months postpartum now involves a progressive program that I have taken time to develop with so much intention and will be assessing as I go, and with the necessary health professional checks and advice along the way with a women’s health physiology which also will be ongoing! This new phase isn’t some crazy step up, its simply simply the next part of my progressive step in my current rehab and restrengthening this mind and body. The bi-product of all of this of course will be some aesthetic change but again the focus isn’t that solely!! Im excited to be entering this phase and Ill be sharing it with you and I hope my journey will and can inspire others to also LOOK AFTER AND TAKE MUCH CARE IN THEIR POSTPARTUM JOURNEY……”

Some women develop frequent, regular contractions that don’t produce any change in the cervix. This condition is often called irritable uterus (IU). IU contractions are much like Braxton-Hicks, but they can be stronger, occur more frequently, and don’t respond to rest or hydration. These contractions are not necessarily normal, but they also aren’t necessarily harmful.

INTERESTING FACT:

In 1851, a Dr. McKenzie wrote a piece in the London Journal of Medicine describing the condition. He started by remarking on the dueling titles of the time— hysteralgia and irritable uterus. The latter coined by a Dr. Gooch in 1831 

In the early 1800’s, “irritable uterus” was actually used to describe a condition in non-pregnant women and unrelated to contractions!

The HEALTHLINE.COM states that:

"There have not been many studies done on IU and pregnancy. In 1995, researchers explored the link between IU and preterm labor and published their findings in the American Journal of Obstetrics and GynecologyTrusted Source. They uncovered that 18.7 percent of women with uterine irritability experienced preterm labor, compared to 11 percent of women without this complication.

In other words: Irritable uterus contractions might be annoying or even scary at times, but they are unlikely to significantly increase the chances of your baby coming too early."

What causes an irritable uterus?
