If you think you may be pregnant, you can carry out a pregnancy test from the first day of a missed period.
Tests that are done earlier than this may not be accurate.
If you don’t have regular periods or do not know when your period is due, the earliest time to do a test is three weeks (21 days) from the last time that you had unprotected sex.
Pregnancy tests are available free from all our sexual health clinics and some doctors surgeries. You can also buy a test from chemists or supermarkets but it’s better to get a test done by a professional health worker to make sure it is done properly.
