My boyfriend and I have sex fairly often and its always unprotected since i am on the pill and he always pulls out. But lately i've been extremely tired, and been wanting to take naps all day because all of a sudden i'm exhausted and i've been peeing like crazy. I know these are symptoms and i've also been having a weird discharge that looks like it has blood. I'm not sure what it is. And i have been feeling a lil constipated which is unusual for me. And my last period was late which since takin my birth control it has been but this last time it was really late and very light. Way lighter than normal. I'm just worried but i dont want to freak my self out and take a pregancy test because i've heard if you are on the pill it can give you a false negative. Anyone have any ideas on what i should do?...
