Ok so my girlfriend and I in a moment of stupidity decided to have sex, unprotected, she is on birth control and has been for as long as we have dated, 3 years, except this week is her period week. We've never had sex unprotected, I pulled out before ejaculation, but knowing that no condom is no bueno I went and bought an ECP (postinor-2 Unidos (we are in Mexico)) she took it within an hour of us having sex. 3 hours later, for some dumb reason we have sex again, unprotected...AGAIN! We get another ECP and she takes it, now I'm freaking out...I'm not ready to be a father, what are the chances my girlfriend is pregnant? Please help me! :(
