My Pregnancy Week 21

Pregnancy Week 21

Your baby continues to grow and develop inside of you. He now measures approximately 7 inches long, and can weigh up to 13 ounces. In the coming weeks, your baby will continue to grow and mature at a fast rate. The hair on his scalp is more visible, and by week 21 he has probably developed eyelashes and eyebrows,

She is waking and sleeping in regular intervals, which you may be able to tell from her movements. She is also swallowing amniotic fluid to help her digestive system mature for life in the “outside world.” Her intestines also start slowly relaxing and contracting this week.

Notice any small, repetitive movements in your abdomen? It may be his first case of the hiccups! Usually, these movements occur for a few minutes at a time. As your baby grows larger, these movements will feel stronger. And remember, all babies are different; some hiccup multiple times a day, while others will do it only once in awhile.

If you are having multiples, the babies are kicking each other as they move around, but don’t worry! They are well protected by the membrane separating them, which is very elastic.
