Week 15 - Heather's Pregnancy Journey

I meant to do this on Friday, but I kept forgetting.
About 13 weeks after conception
Your baby is now weighing about 70 grams and you can clearly see the blood vessels beneath the skin. The heart is pumping 25 quarts of blood a day, which will increase to 300 at birth. During this week, your baby develops skin so thin and translucent that you can see the blood vessels through it. Hair growth on the eyebrows and the head continues this week.
If your baby is destined to be a brunette, the hair follicles may begin to make the pigment that colors the hair. Your baby's ears are almost in position now, although they are still set a bit low on the head. Internally, the bone and marrow in your baby's skeletal system continue to develop. Muscle development continues, too, and your baby may be able to make a fist and bend his or her arms at the elbows and wrists.
I can't believe how quickly this baby is growing. I've been feeling a painful pressue in the middle of my stomach on the surface due to the skin stretching. This kid is trying to make a penthouse in there!
