How Pregnancy Due Dates Are Calculated

Pregnancy is typically measured in weeks from the first day of your last menstrual period (LMP). The standard gestation period is 40 weeks (280 days), though some pregnancies may be slightly shorter or longer.

Due Date = Conception Date + 40 Weeks or Due Date = Last Menstrual Period + 40 Weeks

For example, if you conceived on May 15, your due date would be approximately May 22 of the following year (40 weeks later).

Factors That Affect Due Dates

Several factors can influence your due date:

Gestation length: Most pregnancies last between 38 and 42 weeks
Conception method: IVF or other assisted reproduction may affect timing
Medical conditions: Certain health issues can impact pregnancy duration
