Hi! I'm 18 years old and I have been on birth control for about a year and 3 months or so. I'm two weeks late on my period, and I take the pill every day. My boyfriend and I do have unprotected sex but he always pulls out. My last 4 periods have been extremely weird, I've gotten two really early periods and then these last two have both been late, but not this late. I had brown discharge right around the time of my period but no actual blood. I've been really stressed with all of my college stuff, as well as prom details. I've taken two tests both negative, so I don't understand why I have no period?! Can someone please help me out? :/
