Pregnancy calculator

Want to find out how many weeks pregnant you are? Just use the calculator below and it will automatically work it out for you. All you need to do is enter the first day of your last period.

Marie Stopes Reproductive Choices are able to carry out early pregnancy dating scans which can be performed as early as six weeks after your last period. During the examination we will be able to determine the age of the pregnancy and the expected delivery date (within 3 - 5 days). This service is particularly useful if you are unsure about the date of your last period.

If you wish to continue with your pregnancy it is best to visit your GP who will arrange anti natal care.

If you are not sure what to do or are thinking about having an abortion, call our supportive 24 hour helpline on (01) 830 0630 and we will make you an appointment and answer any questions you may have.
