Getting pregnant is harder than you think and if you’re actively trying for a baby and don’t want to leave anything to chance then our simple ovulation calculator will maximise your chances of getting pregnant.

What was the date of the first day of your last period?

Adjusted cycle length: if you know that your cyle is shorter or longer than 28 days, please adjust the number below.

If you are having problems conceiving then our trying to conceive forum is the place to go for advice and support from other women in the same situation as you and if you do become pregnant, why not talk to other mums about that too?
