PREGNANCY WEEK 37
This week of pregnancy, your baby is about 21 inches in length and weighs at least 6 1/2 pounds.
If your baby was born after this week, he or she would be considered full-term. While the ossification process has
been progressing steadily (cartilage turning into bone), not all of your baby's bones will be ossified by birth.
This is an advantage for both of you, since your baby's skeleton is more flexible when it contains more cartilage,
making the passage through the narrow birth canal easier. Fewer hard bones means fewer hard pokes during delivery.
Changes in You:
Sometimes, the amniotic sac breaks or leaks before labor begins, and the fluid that has
cushioned your baby comes out in a trickle or a gush. Most frequently, your membranes rupture sometime during
labor, often during the second stage. If you are uncertain about whether the leaking fluid is amniotic fluid or
urine (many pregnant women leak urine in the later stages of pregnancy), be sure to have it checked.
