Pregnancy Home > Pregnancy Week by Week
By understanding what happens in your pregnancy week by week, you are taking a proactive role in the healthcare of not just yourself, but your baby as well. Tracking your pregnancy will also help you know what to expect, from changes in your body to the progression of your baby's development. The following article offers an overview of each week of pregnancy, including information about symptoms you may experience and special nutritional needs you may have while pregnant.
During the first week of your pregnancy, you are not actually pregnant. Conception usually occurs about two weeks after your period begins, which means that your period is counted as the first part of your pregnancy, even though you were not pregnant at the time. In other words, week one of your pregnancy begins on the first day of your period.
What many women consider their "first week of pregnancy" is actually considered week three of pregnancy by healthcare providers.

When you are two weeks pregnant, you're still not considered pregnant, although your uterine lining is thickening and your body is preparing to release an egg for fertilization. You are most likely to conceive during this time. However, if you don't become pregnant this month, don't worry -- most women have less than a 25 percent chance of getting pregnant each month.
If you have particular concerns, you may want to schedule a preconception visit with your healthcare provider to determine risks of:
- Genetic diseases
- Environmental hazards
- Lifestyle changes necessary to ensure a healthy pregnancy and baby.
In addition, make sure that you have started taking 400 milligrams of folic acid a day, which has been shown to dramatically reduce the likelihood of neural tube defects, such as spina bifida.
