	From Embryo to Baby in 9 Months

Every baby is different. Every fetus is different. The images we show you may not be your skin color or your fetus's exact size. But they do tell you a lot about what happens over the course of a pregnancy.

This tool links you to information about prenatal tests. Some of these tests are new and not available everywhere. For example, you might not have chorionic villus sampling or nuchal fold ultrasound in your town. The good news it that you still have excellent options, such as triple or quad screening.

If you have any worries about your pregnancy, be sure to talk to your doctor or nurse-midwife. For more information, see the topics Pregnancy, Birth Defects Testing, and Labor, Delivery, and Postpartum Period.
