Surprising facts about pregnancy

Pregnancy changes a women’s body significantly – you need to fit another person inside you! But do you really know HOW much it changes a body? Here are some fun/interesting/painful facts about pregnancy and bringing a human being into this world.

  • The uterus gets bigger – by a LOT!

Everyone knows that a womb increases with pregnancy, but can you imagine how much? Before pregnancy, a woman’s uterus is typically the size of an orange. By the third trimester, it can be about the size of a watermelon.

In fact, it can expand up to 500 times the size during pregnancy.

  • Taller women are more likely to give birth to twins

Researchers have found several genetic factors can lead to multiple births. These include: If you’re over the age of 35, have a history of twin pregnancies, there are twins in your family, or if you’re tall.

According to a study published in the Journal of Reproductive Medicine, women over 167cm tall are more likely to conceive twins.This is because taller women have higher levels of a certain protein released from the liver that is linked to increased ovulation.

  • The longest pregnancy ever recorded was 375 days

The longest time on record that someone has been pregnant for is 375 days. Normally, pregnancy lasts around 280 days, so Penny Diana Hunter’s baby was nearly a hundred days overdue in 1945.

Longer pregnancies are more common than you might think. Many women report being pregnant for 10 or 11 months, rather than the usual nine.

  • The shortest pregnancy ever recorded was 21 weeks and 4 days long

The earliest premature baby to survive was in the womb for just 21 weeks and four days. This 5 month child is in kindergarden and apparently has no health or developmental problems as a result of being born early.

  • There is only one scientifically proven method to bring on labour

While there have been many wacky methods of bringing on labour passed down through generations, there is actually only one which has been scientifically proven to work.

The idea behind nipple stimulation is that it tricks your body into thinking you are feeding your baby, releasing the hormone oxytocin, helping kick-start contractions & progress labour.

It’s important to remember that the evidence is very small and the technique will only work if your body is already primed for labour.

  • A pregnant woman’s blood volume can increase up to 50%

When pregnant, blood volume increases as much as 50% to help supply enough oxygenated blood to the fetus. However, many women can still suffer from lack of oxygen in the blood which can cause “pregnancy brain” or forgetfulness.

  • Women’s heart increases during pregnancy

To help pump all that extra blood around the body, the heart has to increase in size (aren’t bodies amazing). Also, women’s feet can increase by a whole size.

  • At age 30 a couple has a 20% change of conceiving

Certainly some people have higher changes of conceiving and some have smaller. We are all different! However, the overall result from a research has shown that people in their 30’s have 20% change of getting pregnant. This decreases to 5% by age 40.

  • Pregnant women produce more oestrogen in a day than non-pregnant women do in a year

Women grow a placenta — an extra organ — during pregnancy, which produces hormones. At full term, a pregnant woman will produce more oestrogen in a day than a non-pregnant woman will in three years.

  • Babies can be born with teeth

Contrary to popular belief, babies can actually be born with teeth! In fact, studies have shown that for every 2000 babies born, one will have a tooth.

These teeth are known as natal teeth and may be removed by doctors to ensure no choking occurs, as these teeth are often loose.

  • Babies urinate in the womb

Once you are about four months pregnant, your baby begins to urinate inside of you. In fact, they pee up to one liter a day! If that doesn’t gross you out, knowing that your little one drinks it surely will.

  • Babies can cry in the womb

Some of us have always thought babies start only crying after birth. It is now proven that they also cry in the womb. Because of all of the fluid, you can’t hear them.

  • Baby girls develops all necessary eggs in the utero

In utero, baby girls develop all of the reproductive eggs they will ever use. Baby boys don’t develop sperm until puberty.

  • One in third women gives birth with C-section

This number has tripled over past 10 years.

  • Hormones play a big role in pregnancy

Progesterone is nature’s sedative. It gives you a natural lethargy to make sure you do nothing strenuous that may affect the developing foetus.

  • Baby bumps make people smile

It’s not scientifically proven, but you just have to look at the number of people who smile when they see your belly to know it’s true.
