Is it possible to get pregnant when having unprotected sex during the fertile period but using the pull out method before ejaculation happens? My sister is sure that her bf pulled out before the ejaculation happened but she missed her period. She has some cramps and white vaginal discharge since 3-4 days. Her last period was 7th December and before that, it was 7th November. Today is 7th January but she didn't get her periods. Few days back on 3rd January, she also took Ipill. Please help.
