I had unprotected sex on June 11th & maybe 3 hours later I took the plan B pill except I have a period tracker that said I was ovulating on the 12 so I'm wondering if it will work or not . I usually discharge a lot but ever since I've token the pill I haven't really been having any discharge I'm not sure if that's normal or not & it feels like I'm going to get my period but then it goes away ?
