On march 23 I had sex with my gf, she took I pill and got her periods on 30th march. In April month I had sex with her on 1st and 14th with protection and this time she did not have any I pill. She did not get her periods 30th April. But she says her abdomen is paining and some white liquid is coming out every time she's going to the toilet. Does I pill causes delay in periods? I am very worried as this is the 3rd day she's saying about the abdomen pain and white liquid coming out. Doctors, please suggest and what could the reason behind this?
