So 2 days ago me (16 almost 17) and my girlfriend (17) were fooling around a bit, having dry sex i guess as we aren't too ready for proper sex, she was naked but i had my boxers on - and i came. I didn't really think about it until after dropping her off but i suddenly got worried over the possibility she could have gotten pregnant from that.. I'm sure the part of my boxers where i came didn't touch her and i stopped pretty quickly after and pulled away but it was bugging me. I told her, we went to get the morning after pill just to be sure, she took it 14 hours after this happened. What are the chances? She finished her period the day before but we just can't get the worry out of our heads.. and i can't go 3-4 weeks without confirming she isn't pregnant.. any advice or help please because i just can't stop worrying..
