Prenatal Development: Week 10

When you are 10 weeks pregnant, it is very likely that you will still be feeling the early symptoms of pregnancy, but these should disappear shortly. Your waistline may start to grow a little now as well.

Baby Growth
There's lots of growth going on with baby this week, too! Toes, ears and the upper lip are now formed and by the end of the week your baby's vital organs will be developed and starting to work together. During the week, the external genitalia will also start to take shape.

Pregnancy Tip

Prenatal Vitamins
help keep you and your baby healthy throughout your pregnancy. Biotegrity has formulated vitamins that change their nutritional content according to which trimester you are in.

Brain growth increases rapidly by this week - almost 250,000 new neurons are produced every minute in your baby's brain! As external changes, such as the separation of fingers and toes and the disappearance of the tail takes place, internal developments are taking place, too. Tooth buds form inside the mouth, and if you're having a boy, his testes will begin producing the male hormone testosterone. You'll also be relieved to know that congenital abnormalities are unlikely to develop after week 10. This week also marks the end of the embryonic period, so your baby is officially considered a fetus.

Getting Tested
Around this time, your doctor will probably send you for a blood test to find out whether you are immunized against varicella, measles, mumps, and rubella (German measles), as well as to determine your blood type and Rh factor. Rh factor is a substance found in the red blood cells of most people. If you don't have it (Rh negative) but your baby does (Rh positive), complications can result when the baby's blood cells enter your bloodstream. Your doctor can prevent Rh incompatibility problems by giving you a vaccine of Rh-immune globulin at 28 weeks and again after delivery.
