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

Due dates for a August 2027 conception

A pregnancy lasts about 266 days (38 weeks) from conception, so a August conception leads to a due date in April or May. 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-summer conception: what it means for you

An August conception typically means a late-April or May due date. Your first trimester runs into early autumn, and the second trimester covers the winter holidays. The final weeks fall in spring, when mild weather often makes late pregnancy more comfortable — though pollen can be a nuisance if you get hay fever.

Seasons and timing

With conception in August, the first trimester runs until about October, the second trimester covers the months after, and the third trimester begins around January. In the northern hemisphere, that puts the last weeks of pregnancy in winter and the birth in spring (the seasons are reversed in the southern hemisphere). Late pregnancy in winter means taking care on icy paths, keeping up with seasonal vaccines your provider recommends, and planning travel to the hospital around the weather.

Because most babies arrive between 37 and 42 weeks, a baby conceived in August could be born in the month before or after the due month. Your baby’s birthday is most likely to fall between Apr 2, 2028 and Jun 6, 2028.

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.
