My girlfriend and I have been getting carried away the past couple of days. Tonight we started to have sex and I penetrated her and stayed there for a minute or 2 but i didn't have a condom on. I didn't cum...and i have no clue if i had precum....I am now the one freaking out...She was when we were using protection now we don't and she is calm and i am freaking out is there a good chance she is pregnant??? if it helps she just came off her period tuesday...i'm not sure if that has anything to do with fertility or not though...i think i heard it did
