Week 03: Your pregnancy
Your baby's growth: The pregnancy timetable
Pregnancy has an average length of 40 weeks. The first week is your period, and the very end of the second week marks the release of the egg—ovulation. The egg is fertilized early in the third week and typically implants in the uterus 6-12 days after ovulation. Using this dating method, you actually get pregnant during the third or early the fourth week.
You can calculate your due date by adding seven days and subtracting three months from the first day of your last period.
What's happening with you
Ovulation. Right between weeks two and three (about day 14 of a 28-day cycle) an egg will be released into your fallopian tube—this is called "ovulation." Some women can tell when they ovulate by noting mild cramping or pain or increased vaginal discharge. Once the egg has been released, it must be fertilized for you to become pregnant.
