So my girlfriend and I (17 years old) were filling around today, we started by rubbing agonist eachother with our clothes on,she wet my shorts (there thin) (she was wearing pants and thIn underwear) and I took my penis out and rubbed it against her vagina with her clothes on, my underwear had a bit of pre-cum and I got some pre-cum on her pants and whipped it off with my hand, then with my hand I fingered her and she bled after and when she left she was complaining of sharp stomach pains, being tired, nausea and she threw up twice. Could she be pregnant and should we buy the morning after pill in the morning? PLEASE HELP ME !!! Were freaking out !
