PLEASE HELPPP

So my boyfriend and I had sex on Friday which was my last day of my fertile window. We didn’t have a condom but we continued anyways (so dumb I know, I hate myself for it.) it was only for like 2-3 minutes til I got off because I didn’t want to continue without a condom. He didn’t finish. So he just fingered me instead.. fast forward to today I feel sick, bloated and have this bleeding.. my period is supposed to come in 11 days so it’s not my period. Is it implantation bleeding? I’m scared as hell and need help! Thank you!
