I need some answers !! My boyfriend and I had unprotected sex on the last day of my period June 23 and I took plan b less than an hour later. After taking the pill I had brown discharge for over a week ( I read it's old blood). I think it might have extended my period an extra week . We had protected sex two times after that. I was suppose to get my period July 26 but I am now six days late and freaking out . I took 3 pregnancy tests and all came back negative and I feel normal . Please help
