REALLY SCARED HELP

I've been on bc for almost three years and have never missed a pill. Last month during the first week of my pills I forgot to get my percription on Monday and I usually take my pill at 10pm. On Tuesday I took my pill around 230. Now it is about a month later and I had sex with my BF (during the first week of my pills about a day or two after I ended my period) For about maybe 1-2 minutes we had sex without a condom, but I'm still on bc. He did not cum and I made him stop because I was nervous. If anything only pre cum got inside me. I get my period in like 18 days and I'm really nervous. Do you think I am pregnant??
