AM I PREGNANT?

Hi, I just need reassurance I have horrible anxiety and I am on the pill and have been for 7 months and have never missed a day, take it correctly, nothing interfering with it but I had sex with my boyfriend 6 days ago and he came in me! I am worried I am pregnant, my period comes in a few days, I haven’t been having any early pregnancy symptoms but my boobs are sore maybe due to PMS? and I haven’t been sleeping? Am I pregnant? I am really scared, I hope i’m not pregnant because I know that people can get pregnant on the pill
