Using the due date calculator
To find your due date, enter the date of the first day of your last period, and click 'show your due date' - the calculator will do the rest. Pregnancy normally lasts from 37 weeks to 42 weeks from the first day of your last period.
As part of your pregnancy (antenatal) care, your midwife will offer you a dating scan that will give you a more accurate date for the birth of your baby.
