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

Due dates for a November 2026 conception

A pregnancy lasts about 266 days (38 weeks) from conception, so a November conception leads to a due date in July or August. 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 2026. In other years the due date is the same or one day different, depending on leap years.

A late-autumn conception: what it means for you

Conceiving in November gives a due date in late July or August. Your first trimester falls over the winter holidays, so you may be avoiding certain foods and drinks at seasonal gatherings — a common early clue for family and friends. Your third trimester covers early summer, and a late-summer baby may be the youngest in the school year where the cut-off is September.

Seasons and timing

With conception in November, the first trimester runs until about January, the second trimester covers the months after, and the third trimester begins around May. In the northern hemisphere, that puts the last weeks of pregnancy in spring and the birth in summer (the seasons are reversed in the southern hemisphere). Spring’s milder weather often makes the final weeks more comfortable, though pollen can make hay fever worse for some.

Because most babies arrive between 37 and 42 weeks, a baby conceived in November could be born in the month before or after the due month. Your baby’s birthday is most likely to fall between Jul 4, 2027 and Sep 6, 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.
