Questions about a March 2026 conception
If I conceived in March 2026, when is my baby due?
Your due date is between November 22, 2026 and December 22, 2026, depending on the day you conceived. Find your day in the table above. A due date is about 38 weeks (266 days) after conception (ACOG).
Why is the due date about 38 weeks after conception?
Pregnancy is counted from the first day of the last period, about 2 weeks before conception. So a conception on March 16, 2026 gives a due date of December 7, 2026: 40 weeks of pregnancy, but about 38 weeks after conception (ACOG).
Will my baby be born on December 7, 2026?
Probably not on that exact day. For a conception on March 16, 2026, most babies arrive between November 16, 2026 and December 21, 2026, at 37 to 42 weeks (CDC). Your midwife or doctor will confirm your dates.
