hi my gf and i had sex on Sunday may 9th and we used a condom but i kind of cummed inside her with the condom on and when i took it out i dont think the condom broke but the condom was really wet so i dont know if it was her or cause the cum somehow slipped out? i talked to a friend and was suggested to a plan b pill so i gave her a plan b one step pill the next day on monday. and on tuesday she said her breasts are swollen is this suppose to happen? i heard that you can tell if the pill is effective when she starts bleeding but that didnt happen. im really paranoid because this was our first time at sex so i have no ideas what is really going on. both my gf and i had been losing sleep for the past few days. i want to ask what are her chances of getting pregnant?
