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

Due dates for a July 2027 conception

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

Conceiving in July gives a spring due date in late March or April. You would get through the early weeks during summer holidays and spend the end-of-year festivities in the second trimester, often the most comfortable stage. A spring baby means your maternity leave starts as the days lengthen — good for walks with a pram.

Seasons and timing

With conception in July, the first trimester runs until about September, the second trimester covers the months after, and the third trimester begins around December. 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 July could be born in the month before or after the due month. Your baby’s birthday is most likely to fall between Mar 2, 2028 and May 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.
