Chances of pregnant . Please help.

Djambe

Me and my boyfriend were fooling around and I said I wasn't ready to have sex and he said okay

Then was teasing me and entered me with his shorts on (no boxers underneath) and it was damp and he had came earlier (in other shorts) .

Anyway I'm scared I may be pregnant because his bare penis did touch my pelvic area for a short time.

Really stressed out please help. 18 years old.
