Well i'm sure there are a lot of these thread types out there, but i'm sorry i'm going to add another...
My girlfriend and I had sex the middle of last month and towards the end, it's been a week and her period hasn't come...We use condoms all the time and we try to be really careful, it's never broken as far as we can tell. What are the chances that she could be pregnant?
Edit--
my girlfriend also wanted me to ask this too, "what exactly does it mean when people say your breasts get more sensative?"
