Pregnancy rate last day of mestration

Hi , so this is my experice . I had unprotected sex. He didn’t cum in me , but it was my first time having unprotected sex so I got scare & went and got a plan b 3 hours later. Everything was fine, I got my period a week after that. And earlier than expected. We then had sex again 3 or 4 weeks later . And this time it seemed like he didn’t pull out on time. But he says he did. I still got a plan b the next morning because it really scared me. We then had sex again a few days later but this time he didn’t even cum, I got paranoid he would do it again and I pushed him off. A week after that I got my period . But it was 2 weeks early. And it lasted 3 days. It was heavy. And about 4 days later I took a pregnancy test and it came out negative. However 3 weeks later after taking the plan b , I’ve been feeling a lot of cramps and my breast feel weird. Around this time is when I’m suppose to have my normal period. I’m really scared that somehow I ended up pregnant. We haven’t had sex ever since that time , because we stop talking. And I’m scared I’ll end up being a single mom. I’m really scared
