Pregnancy is a life-transforming journey and while there is so much changes that happens during this time, you cannot always be prepared for everything. Here are 10 surprising facts that you did not know were true during pregnancy.

The Nesting Instinct

If you have seen animals look for paper scraps, or take fur out of their own body or collect small twigs and stem to build a nest for their upcoming babies, even if the animals are domesticated, humans do the name. Humans do not take fur or hair out of their body, but we too experience a powerful urge to prepare our home for the baby. We clean it, decorate it and thanks to modern homes, we can now baby proof it do!

Mommy Brain

This happens in the first trimester, when tiredness, morning sickness and other symptoms can make the mother feel worn out and mentally fuzzy, often called the mommy brain. The National Institutes of Health also notes that cognitive function decline in the third trimester of pregnancy, leading to memory problems.

Mood Swings

Premenstrual syndrome (PMS) and pregnancy share several symptoms, such as breast swelling and tenderness, hormonal fluctuations, and mood swings. If you’ve experienced severe mood swings due to PMS, you may notice an intensification of these emotions during pregnancy. It's common to feel joyful one moment and tearful the next as your body adjusts to hormonal changes.

Breast Growth

An increase in breast size is one of the earliest signs of pregnancy apart from your missed period. It happens in the first trimester due to the higher levels of hormones like estrogen and progesterone. The growth continues throughout pregnancy.

Skin Changes

Have you heard about pregnancy glow? This happens because pregnancy women have an increased blood volume, this happens to provide extra blood flow to the uterus and other organs, especially the kidneys. This greater volume brings more blood to the vessels and increases oil gland secretion.

Hair and Nails

During pregnancy, many women notice changes in their hair texture and growth. Hormonal shifts can make hair grow faster and reduce hair loss. However, these changes are typically temporary, and many women experience some hair loss during the postpartum period or after they stop breastfeeding. In some cases, hair growth may also occur in unexpected areas like the face, belly, or around the nipples. Additionally, hair texture can shift, becoming drier or oilier, and some women even notice a change in hair color.

Nails can also undergo changes during pregnancy. Increased hormone levels may cause nails to grow faster and become stronger, but for some women, nails may become more brittle, splitting and breaking more easily. Like hair changes, these nail changes are usually temporary. If your nails are more prone to splitting or tearing, it’s helpful to keep them trimmed and avoid exposure to chemicals in nail polish and nail polish remover.

Your Feet Grow

If you have heard about it, then you already know that it is not just the clothes that do not fit you, it is your shoes too. Extra fluid in the pregnant body also leads to swollen feet. The joints also tend to be looser during pregnancy.

Joint Mobility

Your body also releases hormones like relaxin that prepares your body, especially the cervix for the birth. This loosens the ligament in your body, which may make you less stable .

Varicose veins, constipation, and hemorrhoids

Varicose veins, common in the legs and genital area during pregnancy, result from blood pooling in veins enlarged by pregnancy hormones. They often disappear after delivery. To prevent them, avoid prolonged sitting or standing, wear loose clothing and support hose, and elevate your feet when seated.

Hemorrhoids, which are varicose veins in the rectum, may develop due to increased blood volume and uterine pressure. They can cause pain, itching, bleeding, or stinging, especially during bowel movements. Constipation, caused by hormonal changes and uterine pressure on the large intestine, can worsen hemorrhoids by straining during bowel movements.

Prevent constipation and hemorrhoids by eating a fiber-rich diet, staying hydrated, and exercising regularly. If needed, consult your doctor about stool softeners, laxatives, or creams for relief.

Labor and what goes out of your body

When you are in labor, your amniotic sac, that has fluid that surrounds the baby, breaks or ruptures, which is what is also known as water breaking. For most women contractions start before their water breaks, if not, then the doctor may have to rupture the amniotic sac, in case the cervix is already dilated. Some women may feel the urge to pee, while for some it may feel a trickling their leg.

A blood test is considered the first step towards fertility enquiries, but for many, the results might seem like a confusing jumble of numbers and acronyms. Reports sometimes contain terms like AMH, FSH, LH, AFC, and estradiol, which can confuse patients into thinking that a single "abnormal" figure indicates they are unable to conceive.

The truth is more reassuring, and more nuanced. Fertility experts stress that a single test cannot ascertain a person's fertility. Instead, these markers serve as parts of a bigger picture, assisting fertility specialists in comprehending reproductive health and suggesting the best course of action when necessary.

Fertility tests are guides, not verdicts

The idea that a single blood test can determine whether a woman would naturally become pregnant is one of the most widespread myths. Age, egg quality, ovulation, sperm health, uterine health, lifestyle, and underlying medical issues are some of the factors that actually affect fertility.

Although diagnostic markers offer useful information, they must always be interpreted in conjunction with the couple's overall reproductive profile, clinical history, and ultrasound results.

Understanding the ovarian reserve 'AMH'

Anti-Müllerian Hormone (AMH) is perhaps the most talked-about fertility marker today. It is produced by small follicles present in the ovaries. AMH reflects ovarian reserve, which identifies the estimated number of eggs remaining in the ovaries. High AMH indicates larger ovarian reserve, whereas lower levels suggest fewer eggs. However, it can neither measure egg quality nor guarantee the ability to conceive naturally.

Many women with low AMH can still achieve successful pregnancies, especially if they continue to ovulate regularly. Similarly, women with high AMH are not necessarily more fertile; elevated AMH levels in women also mean Polycystic Ovary Syndrome (PCOS), where ovulation may actually be irregular. For fertility specialists, AMH is useful in predicting the number of eggs that are likely to respond to ovarian stimulation medication, based on which they customize IVF treatment.

FSH determines ovarian function

Our pituitary gland produces Follicle Stimulating Hormone (FSH), and this hormone helps in stimulating egg development.

Usually, the second or third day of the menstrual cycle is when FSH is measured. If ovarian reserve is reduced, higher-than-normal levels may imply that ovaries need more stimulation to mature eggs. From cycle to cycle, the FSH levels change.

LH and the ovulation story

FSH and luteinizing hormone (LH) cooperate to control ovulation. The ovary releases a developed egg in response to an increase in LH. LH levels may be disproportionately greater than FSH in PCOS-affected individuals, which can lead to irregular menstrual periods and ovulation. Instead of using LH alone, fertility specialists assess it in link with other hormone markers.

Estradiol and AFC: Completing the picture

An indicator of ovarian activity during the menstrual cycle is estradiol (E2), a type of estrogen generated by growing follicles. Combined interpretation is crucial since elevated early-cycle estradiol levels can occasionally conceal an elevated FSH.

The Antral Follicle Count (AFC), which is done via a transvaginal ultrasound, is another crucial evaluation. AFC gives an additional indication of ovarian reserve by counting the number of visible tiny follicles in the ovaries.

Indeed, the combination of AMH and AFC provides a more thorough insight than any test by itself.

Fertility evaluation isn't just for women

Female hormone testing frequently receives greater attention, whereas male fertility contributes to roughly half of all infertility issues. A semen screening remains one of the most significant and cost-effective tests, measuring sperm count, mobility, and morphology. When necessary, additional hormonal or genetic tests might be suggested.

Era of self-diagnosis

After getting a test report, many people search the web for quick answers, but those numbers without proper medical context from a specialist can cause unnecessary tension. The fertility markers depend on a variety of factors, some of which include: age, weight, menstrual history, prior pregnancies, medications, hormonal status, and lifestyle. Therefore, understanding parameters like “low” or “high” online may create confusion for individuals. Instead, consult a fertility specialist to decode the report.

For new mothers struggling with breastfeeding, artificial intelligence can offer something doctors often cannot: an answer at 2 am.

But a new report is raising concerns about what happens when those instant responses replace professional medical advice.

A national survey commissioned by Orlando Health found that 51% of women aged 18 to 44 would first turn to an AI chatbot, social media platform or search engine if they had an urgent breastfeeding question.

Only 29% said they would first contact a doctor or lactation consultant, while 21% would turn to family or friends.

The findings highlight a growing challenge as new parents increasingly use AI to navigate pregnancy, caring for their infants and breastfeeding.

Is AI Advice Always Reliable?

AI can quickly explain clinical terms, suggest possible causes for a problem and provide general breastfeeding information. But it cannot examine whether the baby is actually getting enough milk.

“There are certain questions that can't be answered by AI,” said Erynne Bowers, M.D., a pediatrician with Orlando Health Physician Associates.

Bowers said roughly one-third of mothers who come to her with breastfeeding concerns have already received inaccurate advice from AI. Some of the misinformation involves recommendations about how much milk a baby should consume or how frequently the baby should be fed. The expert says that's where generic advice from AI can become misleading and dangerous.

Feeding Pattern Is Different For Every Baby

A baby's nutritional needs depend on several factors, including age, birth weight, growth trajectory, medical history and feeding efficiency.

Doctors also examine the baby's weight gain, hydration, urine and stool patterns, alertness and developmental progress. They may observe the baby's latch, tongue movement and coordination between sucking, swallowing and breathing. These assessments cannot be done by an AI chatbot.

A baby may spend a long time at the breast but transfer very little milk. Another may feed for a shorter period but feed efficiently. A generic feeding schedule therefore cannot explain the entire problem.

How Incorrect Advice Can Create A Cycle?

Experts warn that telling a mother to feed less frequently, for example, could potentially reduce the baby's calorie intake while also lowering breast stimulation.

The report also describes the experience of Florida mother Emily Hunziker, whose newborn son began losing weight despite her efforts to breastfeed exclusively.

She worked with a pediatrician and lactation specialist, used a combination of pumping, bottle-feeding and supplemental formula while continuing to support her breastfeeding goals. Her son is now thriving and growing up well.

Should New Mothers Stop Using AI For Breastfeeding Advice?

It does not mean that new mothers should completely stop using AI. AI can be useful for understanding medical terminology, preparing questions for a doctor or finding reliable resources. But it should not become the final decision-maker when an infant's nutrition or growth is at stake.

Warning signs like poor weight gain, unusual sleepiness, dehydration, persistent vomiting, breathing difficulties, severe pain or a sudden drop in feeding require medical assessment from a doctor rather than an automated generic advice.

Relying excessively on an AI chatbot for answers may delay seeking a physician's help which could, in turn, delay clinical examination and treatment.

Excessive consumption of cow’s milk has been linked to severe iron deficiency in young children. A Queensland specialist has also warned that in the past two years, three toddlers died after developing extreme iron-deficiency anaemia.

According to ABC News, the children were drinking more than 1 litre of cow’s milk a day.

Queensland Children’s Hospital haematologist Dr Sally Campbell said the toddlers were otherwise healthy but developed severe anaemia before infections like viral illnesses took a toll on their health.

“They were drinking more than one litre of cow’s milk per day. This resulted in them developing extreme iron deficiency anaemia and sadly, dying,” Campbell said.

She explained that severe anaemia leaves children with too few red blood cells to deliver enough oxygen to vital organs. A seemingly routine viral infection can therefore become severe and even fatal.

“One small virus can unfortunately be life-threatening when you’ve got a chronic anaemic state,” Campbell said.

Consuming large quantities of milk can reduce a child’s appetite for iron-rich foods like meat, legumes and iron-fortified foods.

Dairy can also interfere with iron absorption. In growing children, whose iron requirements are high, this can gradually push iron reserves to a dangerous low level.

Research from the ORIGINS Project, a large longitudinal birth cohort following around 10,000 Western Australian children, has found widespread low iron levels among young children.

Researchers from The Kids Research Institute Australia, Edith Cowan University, Curtin University and The University of Western Australia published their findings in the Journal of Paediatrics and Child Health in 2025.

Using the World Health Organization’s ferritin threshold, the researchers found iron deficiency in 15% of one-year-olds and 20% of three-year-olds.

Professor Desiree Silva, co-director of ORIGINS and Professor of Paediatrics at The University of Western Australia, has described the problem as a “hidden health crisis”.

She said iron is essential for immunity, oxygen transport and healthy development, while low iron can contribute to tiredness, lethargy, poor sleep and difficulty in feeding.

How Much Cow’s Milk Is Too Much?

Queensland health guidance recommends no cow’s milk as a drink before 12 months. From one to five years, children should have no more than about 500 ml, or two cups, a day.

Importantly, this does not mean parents need to eliminate milk from a toddler’s diet. The concern arises when excessive intake of milk replaces a balanced and nutritious diet.

Campbell said the problem is preventable and urged parents to adopt better dietary habits for toddlers.

Parents must also look for signs of low iron levels in their children. Symptoms like persistent tiredness, poor appetite, development concerns or unusual changes in behaviour should not be simply dismissed as fussy eating or a toddler phase. Severe iron deficiency can develop quietly, making early assessment and treatment important.
