I started my second pack of birth control on the 5th day of my periods and my boyfriend came in me on the 6th day of me being on pills. I finished my pack 3 days ago and I haven't missed a day. We had sex yesterday and maybe an hour after sex I noticed pink discharge. There was no blood or odour. It didn't happen again. I haven't gotten my periods yet but I'm supposed to get it today/tomorrow. I'm not sure if this means I'm pregnant?!!! Please help!!!!!!!
