My girlfriend, 15, and I, 16, just an hour ago had sex for the first time. Both of us were virgins and we used a condom, but the condom broke. I'm almost positive I pulled out in time. She isn't on birth control and all we used was a standard lubricated condom. She hasn't had her period in 29-30 days, but it's been fairly irregular before, happening every two weeks or so.
Could this be because she's mildly bulimic?

Help! What do we do?!
Go to planned parenthood? What?

We live in Minnesota by the way.
And I checked the condom's expiration date and everything; I just bought them this morning too.
