Pregnancy Facts - Week 12

Now that you're in week 12, the chance of miscarriage has decreased dramatically. This is the point of pregnancy that many expectant parents decide to share their news with friends and family. It ain't official until it's Facebook official and it's time to reap in all them likes.


How big is your baby in week 12 of pregnancy

This week, your baby's approximately 2.1 inches (5.4 centimeters) and 0.49 ounces (14 grams).

Your baby's development in week 12 of pregnancy

If you were to poke your belly like you were the Pillsbury Dough Boy, your baby will react. Since your baby is still so small though, it is unlikely you'll be able to feel any movements made in response to the uninvited prodding.


With each passing day though, your baby's muscles get a little stronger. And surprise, surprise, your baby's limbs will grow a little more each day.

In week 9, your baby's internal organs had begun development. This week, they all begin to function at a very basic level.

Those little black dots that are your baby's eyes move from the side of the head to their rightful place on the front of the face.


What's happening in week 12 of pregnancy

Your body is still going through a lot of changes as it continues to adjust to pregnancy. For one, your gastrointestinal muscles have slowed, which may mean constipation, tougher poop and more gas. On the bright side, at least you can now compete on even ground with your partner in unannounced flatulence.


As progesterone keeps being generated by the placenta, your smooth muscles such as the ones in your throat and stomach have loosened which could mean increased heartburn or acid reflux. The good news is that the amount of progesterone being produced has leveled off, so feelings of nausea will begin to subside.


This week, your uterus drops into your pelvic area like the bass in dubstep. A medical professional would be able to feel it by pressing the soft squishy area near your pubic bone.
