What is the pregnancy Due Date Calculator?
You may not yet have a due date from your GP yet, but we understand you are eager to work out when you expect to meet your baby. Our Due Date Calculator will give you an estimated due date.
How is my pregnancy due date calculated?
Unless you have been tracking your ovulation, you will not know for sure exactly when you’ve ovulated and conceived, don’t worry. Our easy to use Due Date Calculator adds 280 days (40 weeks) from the first day of your last period. Simply enter the date of your last menstrual period and your email address, click calculate and the calculator will do the rest.
Can my due date change?
Yes. Unfortunately, no one can say for certain exactly when your baby will arrive. No two pregnancies are the same and your baby will arrive when it’s ready. Only 5% of pregnancies arrive on their due date, with the majority born two weeks either side, somewhere between 37 and 41 weeks. Please remember, this calculator only provides an estimate. You may get a more accurate due date if you have a dating scan at around 12 weeks.
We have given you an estimated due date. Now it’s time to get planning and prep for your baby’s arrival. Pregnancy is an exciting time – but it’s also a nerve-racking one. We look forward to lending you a guiding hand throughout your pregnancy and being with you every step of the way.
