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

Due dates for a April 2027 conception

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

An April conception points to a late-December or January due date, so a baby could arrive over the winter holidays or as a New Year baby. Your third trimester falls in autumn, with cooler days that many people find easier in late pregnancy. Consider how winter weather might affect the journey to your hospital or birth centre.

Seasons and timing

With conception in April, the first trimester runs until about June, the second trimester covers the months after, and the third trimester begins around September. In the northern hemisphere, that puts the last weeks of pregnancy in autumn and the birth in winter (the seasons are reversed in the southern hemisphere). Autumn’s cooler days often make the final weeks more comfortable; it is also a good time to ask about seasonal vaccines.

Because most babies arrive between 37 and 42 weeks, a baby conceived in April could be born in the month before or after the due month. Your baby’s birthday is most likely to fall between Dec 2, 2027 and Feb 4, 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.
