Pregnancy normally lasts around 40 weeks from the first day of your last menstrual period. Confused already? Forget complicated charts - try our handy due date calculator to help you work out when you can expect your baby to arrive.
Just enter the first day of your last period and we’ll estimate your baby’s due date. Some women have menstrual cycles that are not exactly 28 days though, so if your cycle is longer or shorter than 28 days, please adjust the number as required.
Please remember that this is just an estimate and that the majority of women do not give birth on their due date.

Are you trying for a baby? Getting pregnant isn’t always as straightforward as it sounds, but you can increase your chances by finding out when you’re most likely to ovulate.
Forget complicated charts, just select the first day of your last menstrual period. Then, tell us:
- 1. The average length of your cycle
- 2. The average length of your ‘luteal phase.’ This means the part of your cycle which starts at ovulation and ends the day before your next period. If you are unsure, just leave it as 14 days.
We’ll then tell you which days you’re at your most fertile, including the date ‘most likely’ for you to conceive.
NB: Please bear in mind that these are just estimates, based on a regular menstrual cycle. If your cycle is irregular this may not be the most accurate way to work out when you are ovulating.
