Hi, i had unprotected sex with my girlfriend on 31st July and she took Postinor , 2 tablets at once on the 3rd August. And we had unprotected sex again on 4th August, the next day. So, is the pill still effective? Because eversince she took the pill, she has been having side effects like nausea, tiredness, abdominal cramps till today, 5th August & she just found out too that she has slight bleeding / discharge on her Vagina. Is it something serious & is there any chances of her getting pregnant?? Im very worried . Hope to have some answers ASAP. Thank you so much
