Me and my girlfriend had unprotected sex on 3rd May and I gave her unwanted 72 within 2 hours. Again we had unprotected sex on 13 May and this time also I gave her the unwanted 72 within 2 hours. She was supposed to have her periods on 15 to 16 may. Last month she had her periods on 19th . What is happening? Is she pregnant?? Or due to the side effects of unwanted 72 her period is delaying. She is 25 yr old.
