Greetings respected doctors! my girlfriend and I had sex for the first time in april 30 recently, and after a gap of 16 days, she suppose to have her menstruation at date 14 of may this month, but there's still no sign of her menstruation, we did have an unprotected sex, but I didn't ejaculate and we were doubting she'll be pregnant, so I let her take ipill to stop our fear of getting her pregnant. Please doctors help us! thank you!
