I don’t believe I’m pregnant, but I want to make sure.

Patient: Yesterday, my boyfriend and I were on the couch and, for lack of a better term, “making out”. Furthermore, I found my legs wrapped around his mid-section and he was erect. We both had on clothing, but I felt his gentalia ever so slighty push against the lips of my area. Ever since, my lower abdomen has been feeling odd. I have two weeks or so until my period, but I;m not sure if my stomach distress is from stressing over this. Please let me know.
