hi,I and my girlfriend had sex on her ovulation day,she took the pill on Tuesday 6pm,we then had unprotected sex on Thursday,my question is is there any risk of pregnancy??

Dear Anon.

Thank you for writing.

Do you mean emergency contraception? This is meant to be taken in emergencies, not in preparation for planned unprotected sex. She will have to wait and see.

Emergency contraceptives are up to 95% effective when taken as prescribed within the first 24 hours, so the risk is very small. Side effects can include stomach aches, headaches, nausea and a general feeling of being unwell. Symptoms usually start 2-7 days after taking the medication and may or may not include bleeding or spotting. Not all women get symptoms. If she doesn't get her next period within a week or so of its expected date, a pregnancy test is recommended. It can cause her period to be early or late, have a lighter or a heavier flow.
