A April due date is a window, not a deadline

Full term starts at 39 weeks, so for a April 2027 due date it begins as early as March 25, 2027. Late term runs until 41 weeks 6 days, as late as May 13, 2027.2 In an Australian study of births after spontaneous labor, only about 5% arrived on the estimated due date, and about two-thirds within a week of it.3 So a April baby may well arrive in March or May.

Your due date may also move once, after an early ultrasound.4 Read how accurate due dates are.
