Interactive Tool: From Embryo to Baby in 9 MonthsSkip to the navigation
What does this tool help you learn?
You can use this tool to discover the amazing changes that happen during a pregnancy. Get a close-up peek at the early embryo. See how much a growing fetus changes every few weeks. Read about what's new every month.
You'll also find links to helpful information about testing, healthy pregnancy choices, premature birth, and labor and delivery.
What should you keep in mind?
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 translucency ultrasound in your town. The good news is that you still have excellent options, such as triple or quad screening.
