I had my period on the 24th of Dec.Had unprotected sex on expected ovulation day(6th Jan) and took P2 after 24hours.One week later I'm having painful cramps (for 2 days)with irregular brown discharge.Am I pregnant?

Dear Anon.

Thanks for your question.

Emergency contraceptives are up to 95% effective when taken as prescribed within the first 24 hours. Side effects can include stomach aches, headaches, nausea and a general feeling of being unwell. Symptoms usually start 3-7 days after taking the medication and may or may not include bleeding or spotting.
Not all women get symptoms. Some get many or a few or none. If you don’t get your next period within a week of it’s expected date - a pregnancy test may be necessary although the risk is low.
