Week 37
Your Baby's Development
By now, your baby has developed enough coordination
to grasp with the fingers. 
If shown a bright light, your baby may turn toward it in your
uterus.
He or she continues to gain weight — developing fat at the rate of half an ounce (14 grams) a day. In general, boys weigh more than girls at birth.
Your Body
After this week, you may lose the mucus plug that
sealed off your uterus to protect it from infection. The mucus plug (which can be
lost a few weeks, days, or hours before labor) can be clear, pink, yellowish, or tinged
with blood (this is called "the bloody show"). As the cervix dilates in preparation
for birth, the plug is discharged from the body. Be sure to speak with your health
care provider about any discharge you have.
