So I am already on birth control and I would say I take it pretty regularly, although I started it late this month because they were out of it in the pharmacy. Anyways, I am a virgin(lol) and I was with a guy. We were grinding (he had his underwear on) and he fingered me. He doesn't think he touched his penis and then put it in me. But he's scared his underwear may have had some moisture on them. So he freaked out and I went to the store about an hour later and bought some Aftera 1-step morning after. I took it (on Tuesday when this all happened) I was supposed to get my period on Thursday or yesterday. So far, nothing. What are the chances i'm pregnant? Even though we did this the week I was supposed to get my period. Please explain to me.
