Am I pregnant? Is it late to take a pill? What do I do?

I had unprotected sex (my first time) but I was never penetrated. My period is always on point but what a coincidence that in the same month I had “sex” my period is late. Guys I’m so scared I’m not ready to be a mom I’m still a junior and I regret everything I did and feel ashamed of myself because I always wanted and want to wait for marriage.

**********************UPDATE*************

I did some research and found that I can get pregnant without having sex even though it is rare. I took two pregnancy test and both came out negative, I took them in the morning because that’s when it is best to take it because of a hormone (HGC). My period is 8 days late and I don’t know what to do now, should I trust the tests?
