My girlfriend's last menstrual date was 3 July 2017. Me and my girlfriend had unprotected sex on 31st July 2017. After having sex she took unwanted 72 and now its been from 2-3 days she is having cramps in stomach and pain in vagina, when she is lubricating a white fluids coming out from her vagina. She did not got her periods till now. So is there anything major problem? Is this normal or is she pregnant?
