You’re 17 Weeks Pregnant!

What’s Happening This Week:

Your Baby’s skeleton is continuing to change from soft cartilage to bone by the process called ossification and they can even move their joints.

Baby’s head is still big in proportion with the rest of their body. Eyebrows, eyelashes and the hairs on your Baby’s scalp continue to grow. Your Baby’s eye lids remain closed but the eyes beneath are growing larger.

Baby weighs 5 ounces now, and he’s about 4 1/2 to 5 inches long from crown to rump and is about the size of a pepper.

Baby’s sweat glands are starting to develop and their circulatory and urinary systems are working perfectly. Your Baby practices respiratory movements now and amniotic fluid passes into and out of the future air passages of the lungs. Although you aren’t able to hear them your Baby can have bouts of hiccups.

Fat is also beginning to develop under Baby’s skin. This fat helps Baby feel energetic and warm.

This is a time of rapid growth for your Baby and now he or she can hear sounds outside your body. Some loud sounds may even make baby jump.

Umbilical Cord

The umbilical cord has grown longer and thicker. You will see in this 3D image of a 17 week fetus that the umbilical cord appears to be near baby’s neck. This is often commented on by parents during an ultrasound examination. The cord is quite long and is helical in nature much like a telephone cord so even if the cord becomes knotted or close around baby’s neck it won’t be a problem while baby lives in the womb.

What’s Happening With You This Month?

Things continue to change for you too. As your tummy expands you may feel the need for new clothes. You will be spoiled for choice as there are many maternity shops that carry a variety of different style clothing but even just a few well chosen items that you can mix and match should get you through.

Other important pieces of clothing to consider at this time would be a supportive bra. Getting a bra that is measured by a professional fitter might help with comfort. A new pair of comfortable shoes might be helpful at this time, something that will allow for a bit of swelling and keep you steady on your feet.

Layering clothing may be a good idea as you might feel warmer one moment and cooler the next! Using layers will help control your body temperature and perspiration.

If you have trouble with varicose veins you may want to invest in a pair of maternity supportive stockings that have a panel in the front that will stretch over your expanding tummy. It’s best to keep in mind not to wear anything that restricts blood flow as this will make your varicose veins worse. You may even have to put the stockings on before you get out of bed in the morning, it’s a bit of a pain because then you have to bathe at night but it really helps with swelling and swollen leg veins.
