12 Weeks Pregnant – Your Body and Your Baby

12 Weeks Pregnant | Symptoms and Your Baby

At 12 weeks pregnant, you’re at the end of the first trimester!

Your uterus has now grown above your pelvis and is taking some pressure off your bladder.

You should notice that you don’t need to go to the toilet quite as often, and this will last until baby is quite a lot bigger.

Between 11 and 13 weeks pregnancy you may have decided to have an ultrasound to check on baby’s growth and development, so you may get to see baby this week!

During the ultrasound, the sonographer will measure baby and confirm your due date, plus or minus seven days.

12 Weeks Pregnant – Your Body

Now is a great time to treat yourself to a new pair of comfy pants. You may have noticed your regular clothes are starting to feel uncomfortable. Some women may feel a bit down about their appearance at the end of the first trimester. They know they are pregnant and have a little bump, but to the outside world, it isn’t clear if it’s a baby bump or your belly. On top of that, hormones may have been unkind to your skin too, so it’s understandable if you feel a little worse for wear.

If you’re one of those women who feel self conscious — please be kind to yourself! This too will pass. If the finances allow, treat yourself to something special you enjoy and you will feel so much better. A pregnancy massage is perfect for releasing stress and tension.

12 Weeks Pregnant – Your Baby

When you’re 12 weeks pregnant, your baby’s sex organs are distinguishable, but still incomplete. Your baby’s eyes are almost in the correct position in relation to its head, as are its ears.

The lungs are developing and primitive breathing can be seen. Vocal cords begin to form. The amniotic fluid that your baby swallows is now passed out through its bladder.

Your baby’s bones, which until now were soft, are starting to harden, including the ribs and spine. Its arms are in proportion with the size of its body. Toes and fingers are formed.

Movement will not be felt yet but your baby is still kicking away. He or she can now curl their toes, rotate their ankles and wrists, press their lips together and make facial expressions, like frowning and smiling.

At 12 weeks pregnant, your baby measures approximately 4-5.5cms long, weighs around 14 grams and is the size of a lime.

Relationship Tip: track these development milestones together! It’s a great way for you and your partner to connect, learn and share during pregnancy and bond with your baby.
