What do I do now?

After chatted to a guy on Facebook we met for the fest time last night , after chatted he asked if I would like to have a few drinks at his home , I said yes and I felt safe because we have lots of mutual friends on Facebook and he works near me. So we went to his and chatted and drank he was becoming more tipsy than I and he kissed me , we kissed and he became more intense and I told him I don’t sleep with a guy on the first date he said that’s ok we are just kissing but he became more intense again and taking my clothes off I said no then he sat back panicking like he was going to cry he looked scared and kept on saying sorry sorry I’m sorry , I was a little shocked. The night went on and yes I ended up sleeping with him. He wanted me to stay in the morning but I wanted to leave because I had things to do , I told me to text him when I get home and I did he then texted saying just realised we didn’t use protection I know it’s a big thing we had done and I have been single for over two years and no sex and I’m clean because I had a test. I told him this and he said I didn’t mean that , obviously he meant pregnancy which I’m on the pill. At the moment I’m feeling upset with myself. What should I do now
