Frequently asked questions
If we conceived in July, when is the baby due?
A baby conceived in July is due between 24 March and 23 April of the following year. The table on this page gives the due date for each day of conception, and the calculator works it out from your own date.
Why is the due date 40 weeks if the baby was conceived 38 weeks before?
Pregnancy is counted from the first day of the last period, about two weeks before ovulation and conception. So the 40 weeks include two weeks before the baby was conceived.
Will the baby come on the due date?
Probably not exactly. Only about 4% of babies are born on their due date, and most arrive in the two weeks before or after it. An early scan gives the most reliable date.
