Sex everywhere.

So I'm not on birth control and I just wanted some second opinions on stuff so I can just chill out. Please no judging, I just like to have a good time. So about a month ago my friend and I had unprotected sex and he came on my chest, and not inside of me at all. This is also the day my period ended. Just to be safe, I took a plan b pill the next morning. Then a week after taking the pill I spotted for about a week, and then we had sex again with a condom about 2 weeks after that. The condom broke but he didn't cum at all this time, we just stopped. Now my period came right on time, but has been light, I think because of the spotting in between periods. So now today was supposed to be the last day of my period, but it hasn't stopped yet. And today I had unprotected sex for like 30 sec, and I'm still bleeding from my period a little. He didn't cum at all today. My stomach is hurting tonight and I'm not sure why, but it's making me worry. Im not pregnant, right?
