Your baby’s development

At 12 weeks pregnant your baby is now around 6cm in length. Their face is beginning to look more human and their eyes, which started on the side of their head, have moved closer together on their face. Their ears have taken up position on the sides of their head. Your baby’s hair is now beginning to grow and fingers and toes have small soft nails, while their mouth has 20 tiny buds which will become baby teeth. They might even start to suck their thumb and they’re much more active. Their vocal cords are complete, though will go unused until their first few seconds in the outside world!

You & your body

This is the time most people start sharing their good news. Which is lucky as you may start to show very soon!

That’s because, around now your uterus grows out of your pelvis and rises above your pubic bone. From now on it will grow into your abdomen, creating your beautiful bump. A lot of mums say that this is the time their pregnancy starts to feel more real.

As your pregnancy progresses your uterus will get heavier until, at nine months it will weigh up to 2 pounds (compared to 2.5 ounces before you became pregnant)! But don’t worry – it’ll be back to its pre-pregnancy size within weeks of the birth.

 

Did you know?

Throughout pregnancy you’re entitled to free NHS dental care and prescriptions, and until your baby’s one year old, too! If you haven’t already been given a form to apply for an exemption certificate, ask your midwife so you can get it as soon as possible.
