Someone please help me. I'm freaking out right now

Justine • love yourself♥️
So I had sex on a Saturday, (finished my period) 
and then I got scared so I took a A Plan B, and then I moved on and I went to the club and I saw one of my exes and it was the following Saturday and we had sex and he put it in without a condom, and it hurt when he was putting it in because it didn't fit then he forced it. And then after the force, he put on a condom and he rode me for like two minutes and then got off and then just had some personal issues or whatever it doesn't matter (his ex) and then the next day I'm bleeding and I feel dizzy. I took a plan b again that day after we had sex.. It's been three days since then and I am bleeding at a medium and I'm really scared.
