So, feb 9th I had unprotected sex and my bf came inside. the next day i got plan b. and about 2 to 3 days after that i got my period. everything was regular, 7 days. my cramps were a bit stronger than usual but nothing that I havent experienced before. after my period, around 3 days later, i was spotting a little. i didnt think about it too much because it happened before and i searched online and was informed it could just be blood that was not fully discharged and in the past everything was fine. so after 2 days my spotting ended. but now im spotting again. I don't know whats going on, can someone give me some ideas on what it could be.
