soo i took plan b exactly a month ago after unprotected sex. i wasn’t sure if he came in me. i wasn’t ovulating or near my fertile window. i was five days late and i finally got my period (i think) on monday. the first day wasn’t bad, i barely had a flow. but the second day it was super heavy with some blood clots. then it kind of slowed down as the day ended. today it’s not as heavy as yesterday and not as much blood clots, but it’s still bright/ dark red. but it slows down. this has never happened to me, usually it gets heavier a few days after i start. idk if this is my period or implantation bleeding ?? how would i know ?? i know plan b can cause your cycle to become messed up, i’m really confused and kinda worried. it was my first time taking plan b, so i don’t really know what to expect.
