Helpppp!

Okay so Me and my boyfriend had sex last Saturday without a condom we did it 4 different times that day . He pulled out and finished on my butt everytime ( lol I know TMI) then we went and got a plan b that night and I took it. But I’m also on the pill and I take it the same time everyday religiously , now last month around July 11 we had sex and the condom broke and he hadn’t finished but I got my period in the next few days but it was kind of light , now my next period is expected in about a week and my stomach has been cramping for 2 weeks , pregnant ? , cyst? I’m so scared and confused !
