Actually my girlfriend had her periods at 25th Nov. Then we had unprotected sex accidentally on 21st dec and had to take unwanted 72 right after that. Then she had withdrawal bleeding on 26th Dec. Then again as it was her bday so we were drunk and had sex unprotected on 10th Jan and took the same pill right after sex. I know this is not right taking such huge dose of hormones please let me know how can I make sure the pill has worked and we are out of these as we have to concentrate on our studies too.
