If I Get Pregnant in February, When Am I Due?

Due dates for a February 2027 conception

A pregnancy lasts about 266 days (38 weeks) from conception, so a February conception leads to a due date in October or November. The table gives the estimated due date for each possible conception day, and the date a home pregnancy test is usually reliable — about two weeks after conception, around when the next period would be due.

Dates for 2027. In other years the due date is the same or one day different, depending on leap years.

A late-winter conception: what it means for you

A February conception usually means an October or early November baby. You would spend the third trimester in late summer and early autumn, when the heat is easing. Many families find that an autumn arrival leaves time to prepare over the summer, and a due date close to Halloween makes for some memorable birthday parties in years to come.

Seasons and timing

With conception in February, the first trimester runs until about April, the second trimester covers the months after, and the third trimester begins around August. In the northern hemisphere, that puts the last weeks of pregnancy in summer and the birth in autumn (the seasons are reversed in the southern hemisphere). Late pregnancy in hot weather can be tiring: plan for shade, light clothing, plenty of fluids and rest with your feet up.

Because most babies arrive between 37 and 42 weeks, a baby conceived in February could be born in the month before or after the due month. Your baby’s birthday is most likely to fall between Oct 4, 2027 and Dec 5, 2027.

Conception dates are estimates

Few people know the exact day they conceived. Conception happens within about a day of ovulation, which can be up to five days after sex. If you know the first day of your last period, the Due Date Calculator is the standard method. For any month at a glance, see the Conception Due Date Chart.
