Am I overthinking?

My boyfriend and I have had sex in the past 2-3 weeks about 4 times. We used a condom all times and he never came inside of me. I'm super worried about the risk and I'm supposed to start my period Monday. I have been a little bloated and I started breaking out. I think I'll be fine but I'm not sure...any thoughts? Plus I'm worried about freaking out and making my period late...
