Pregnancy Calculator - Due Date Calculator

Pregnancy Due Date Calculator

Our pregnancy calculator is very easy to use. Simply select the date of the first day of your last period to start calculating your due-date.

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.

If you are recently pregnant and wondering ‘when is my due date?’ Just enter the first day of your last period and our pregnancy calculator will 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.

Pregnancy Week Calculator

Want to know which week of pregnancy you are in? Our pregnancy calculator will do that too. Follow the prompts for due date calculation and we’ll also let you know the approximate week of your pregnancy.

Please remember that the pregnancy calculator just gives an estimate and that the majority of women do not give birth on their due date.

To the lady with an 11 wk old

To the lady with an 11 wk old asking if she could be pregnant after having sex 4 wks after having baby, it happened to me 7 yrs ago, we thought we were safe because I had just had a baby but (so my MW said) I was actually more fertile. Now we have 2 daughters who are a little over 10 months apart, don't panic it wasn't as scary as I thought, although very tiring (but we also had a 2 yr old at the time) as long as you have a lot of support you will be fine.

1st timer

i'm so scared, I've just found out i'm pregnant after trying for the past 10 years. I was pregnant before with triplets but something went wrong and i misscarried all of them and yeah now i'm pregnant i'm scared the same thing will happen again just hope this one is a fighter


I've just had a little girl, she's 11 weeks tomorrow. Me and my partner (her dad) had sex when she was about 4 weeks. Now I've been feeling sick and headaches... I've taken 2 pregnancy tests and both come back possitve. Could my hormones still be there or am I pregnant again? Really scared!

Hi i am 6wks pregnant with my 3rd child. I'm a mixed bag really, nervious & excited. I honestly did'nt see my husband & I having another after nearly 8yrs since our youngest child. I thought it was my time to branch out into my own career, however, i do remind myself that the yrs of experience & maturity we have now can only work in our favor. Plus my relationship with my two chidren has grown so much more, so i guess it can be seen it as a very precious miracle :)
