Pregnancy Week By Week
When you're pregnant, the more you know about all of the changes going on inside your body, the better prepared you'll be to handle them. Pregnancy Week By Week will guide you through this exciting time in both your and your baby's life.
If you suspect that you're pregnant, you may want to take a look at "Am I Pregnant?". Another great place to start is Nutrition During Pregnancy.
For the purposes of this guide, we will count Day 1 of your pregnancy as the first day of your last menstrual period. Since the average woman's menstrual cycle is 28 days, that means that conception occurs at approximately 14 days.
Therefore, we'll start at Week 3. You can click on the links below or scroll down to see Weeks 3 through 9.
