Hello Doc, me and my girlfriend we have an unprotected sex and she have taken Postinor 2 few hours after that. Here s some detail, she have her period on 4th April, and we have sex on 9th april, and taken the pills. Then 17 april she have bleeding similar with period, lasting for 3 days. And today already 17 may, but her period still hasn t come. She have symptoms as increase appetite, and feeling cramp on the lower abdomen, similar as before she had her period before. We still didn t take pregnancy test yet. What would you say doctor, please help us. Thank you.
