Understanding Pregnancy Weeks

Pregnancy is typically divided into three trimesters:

First trimester: Weeks 1-12 (conception to 3 months)
Second trimester: Weeks 13-26 (3-6 months)
Third trimester: Weeks 27-40 (6 months to full term)

Formula: Due Date = Last Menstrual Period + 280 days (40 weeks)

For example, if your LMP was January 1, your estimated due date would be October 31.
