I and my girlfriend ,both of us aged 19,had unprotected intercourse and for emergency post coital contraception, she took a single dose of 200mg mifeprestone 6 hours after the intercourse. We posted a query about its efficiency on the internet and it was said to be okay, now the thing is ,her periods is supposed to come today and today all she got was a thick white vaginal discharge. Maybe we should wait for a few more days?. Anyway what does this mean??. Is she pregnant??. Should i or she be concerned??
