Due Date Calculator. This interactive Due Date Calculator will help you estimate the date your baby will arrive. Pregnancy usually lasts 280 days (40 weeks) from the first day of the woman's last menstrual period. This calculator is a general guide: every pregnancy is unique, and sometimes babies arrive sooner or later than expected. Always talk to your health care provider about your due date. Once you're pregnant, be sure to have regular checkups by a doctor, certified nurse-midwife or other health care professional during the course of your pregnancy.
Pregnancy / Gestation Calculator. Pregnancy normally lasts from 37-42 weeks from the first day of your last period. Use our pregnancy gestation calculator to work out when you might expect your baby to arrive, and at which stage of pregnancy you are. This will give you an approximate idea and as part of our ultrasound services, we can offer you a dating scan that will give you a more accurate date for the birth of your baby.
