I had sex with my gf without any protection on 5th july and her last menstruation cycle was on 15th june. She took Unwanted 72 within 24 hours after sex. But today is 22nd July, still she have not getting her period. She felt Pain from 16th july but not getting down. I am very worried about that. What are the chances of Pregnancy? and Why she felt pain if not getting period?
She should indeed go ahead and do a home pregnancy test to learn if that is what is going on, but it sounds more like just the results of the morning-after pill.
