Okay I know I've asked certain similar questions but I haven't gotten any that actually truely explain, what's going on

Last Monday (March 31st) I had sex with my boyfriend and the condom had broke,no longer than 45 mins later I consumed both Plan B pills, I never felt sick or anything, on Thursday I woke up to blood, like the same amount I get when I get my period, but it couldn't be my period cause I got my period March 24th and it ended April 1st. My boyfriend didn't ejaculate in me, and it's now Sunday, and I've been having so much bleeding I know spotting is an affect of Plan B, but there's so much that I change my pad atleast 4 times a day, and there's blood clots, is this just the side affect or am I getting my period for the second week in a row? I'm supposed to get my period April 22-24th ish, will I get it again then? Or what :S PLEASE HELP ME I'M REALLY WORRIED.
