How Pregnancy Due Date Calculation Works

Naegele's Rule

Due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (LMP). This is the standard medical method used worldwide.

Your calculation: 11 Nov 2025 + 280 days = 18 Aug 2026

Cycle Length Adjustment

For cycles different from 28 days, the due date is adjusted. Longer cycles add days, shorter cycles subtract days from the standard calculation.

Your cycle: 28 days | Adjustment: 0 days | Final due date: 18 Aug 2026

Conception Date

Conception typically occurs around ovulation, approximately 14 days after LMP for a 28-day cycle. This is adjusted based on your cycle length.

Your conception date: 25 Nov 2025 (LMP + 14 days)

Pregnancy Weeks

Pregnancy is counted from LMP, not conception. You're currently 0 weeks and 0 days pregnant, in the first trimester.

Current status: 0w 0d | 0% complete | 279 days remaining
