Your Baby's Development: Week 10

Week 10
You are now 10 weeks pregnant. This week, you could still be feeling some early symptoms of pregnancy. These should disappear soon. You may also notice that your waist line is starting to widen.

How Does My Baby Look?
Baby's toes and ears as well as the upper lip are formed now. The external genitalia will start to develop this week. And if you're pregnant with a boy, his testes will begin to produce the male hormone, testosterone. Other internal developments are happening, too.

Pregnancy Tip

Prenatal Supplements
Giving your body the right combination of nutrients for the right stage of pregnancy, Biotegrity's Stage 1 are based on the newest Dietary Reference Intakes for pregnancy.

Baby's Brain Growth!
The tooth buds are forming inside baby's mouth. By the end of the week, baby's vital organs will have been formed and will start to work. The baby's brain growth will quickly increase - in fact, some 250,000 new neurons will be produced inside baby's brain every minute! After this week, it is unlikely that any congenital abnormalities will develop. Your baby can now be officially called a fetus, as Week 10 ends the developmental stage called the embryonic period.

The Rh Factor
At this point in your pregnancy, your health care provider will ask you to get a blood test. This test will determine if you have been immunized against measles, mumps and rubella (the German measles) as well as varicella. This blood test can also confirm your blood type and Rh factor. Rh factor is found on the surface of red blood cells in most people. If you are Rh negative, you do not have this Rh factor. However, if your husband is Rh positive, there is a chance the baby could also be Rh positive. In cases of an incompatibility, your doctor will give you an Rh-immune globulin when you are 28 weeks pregnant and once again after you give birth.
