My Pregnancy Week 21

Brought to you by
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.

  19. Yoana says:

  20. Shana says:

    Instead of waiting for the ultrasound, I completed the blood test to find out I’m having a girl.

  21. Shana says:

    I really don’t feel much yet. Just upset stomach and burning sensations. Sometimes she’ll flurry. My first full term pregnancy and I really don’t know what to expect. I’m hungry all times of the day and night.

  22. Nancy says:

    I’m 20 weeks and 6 days and baby kicks/hiccups as I just found out so many times! Is good to feel her move though.

  23. ToBeMom says:

    At 21 weeks, the baby kicks/hiccups a LOT! My husband can feel her too when he puts his hand on my belly!
    On the flip side, i developed a bad cough a couple of days ago and havent taken any medicines. Managing with gargles and halls. Haven ob/gyn appointment tomorrow and hope the doc confirms there is no harm to the baby because of all the coughing.

  24. LaraPineda says:

    Well I am nervous my baby don’t move very much should I worry?

    • Depending on how many weeks you are. Movement should start being felt at 14 weeks. And is very minimal at first so is easy to miss. As you progress you should feel harder movements/kicks. If you are any farther along than 20 weeks and not feeling it. Tell your doctor!
