so on monday i took a plan b cause my bfs condom broke inside me with precum, and i was suppose to be getting my period 4 days after monday so on thursday but i haven’t gotten it, i was told that i should’ve never took the plan b cause i was not ovulating plus i was a couple days away from my period. but on thursday me and my bf decided to take the condom off for a couple minutes and i wiped the precum and stuff off and i was told plan b stays in your system for 5 days so am i okay? i’m not pregnant right? i can’t tell if this is spotting from plan b, my period starting, or implantation bleeding? please help me.
