Pregnancy Week 16
Congratulations -- you are in the second trimester! Your baby is now at 13 weeks gestation and is about 4 inches long from crown to rump (5 inches head to toe) and weighs about 1 1/2 ounces. About now, a small amount of hair is growing on your baby's head and eyelashes and eyebrows start to emerge. 112) Your uterus is approximately half way from your pubic bone to the umbilicus.
Advice for Mom
Your uterus may practice contracting about now. These are called Braxton Hicks contractions. If you have more than 5 in an hour or experience severe backache and cramping, contact your doctor. You may have trouble concentrating, you might drop things, forget things. You feel "not all there" and have new feeling of calmness. If you are feeling angry or emotional, it is normal!
