So I took a plan b two weeks ago and I’m on birth control. Had sore boobs, cramping, and nausea up until my period this Thursday. It had be extremely heavy and then Friday me and my boyfriend had sex and it stopped completely. I lost all my symptoms except for heavy cramping. Sunday I put a tampon in but what came out was tan and looked like old blood and this came out. What could it be? Every pregnancy test I took was negative including the one on Sunday
