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.
But for the sake of a date, everyone's pregnancy is calculated based on an average. Therefore when you miss your first period, youâre already 4 weeks pregnant. Okay, got it, but how many weeks am I, you askâ¦. To find out how many weeks you are, use our pregnancy calculator. It will give you an estimated due date and estimated date of conception. It will also tell you how many weeks pregnant you are, and how long you have to go until you reach the end of full term pregnancy at 42 weeks. What If I Donât Know When My Last Period Was? If you donât remember when your last period arrived or if youâve not had a period for a while, you can book an early pregnancy ultrasound to try and work out how many weeks pregnant you are.
