How is the Due Date Calculated?
The due date is typically calculated based on the first day of your last menstrual period (LMP). The standard calculation adds 280 days (40 weeks) to the LMP date. If you know your conception date, the calculation adds 266 days (38 weeks) to that date. However, these are just estimates.
Pregnancy Trimesters
Pregnancy is divided into three trimesters, each lasting about three months:
- First Trimester (Weeks 1-13): Major organs and body systems of the baby are forming.
- Second Trimester (Weeks 14-27): You may start feeling the baby move. The baby's organs continue to develop.
- Third Trimester (Weeks 28-40): The baby grows rapidly and prepares for birth.
