I had protected sex with my boyfriend yesterday (we used a trojan condom), and he is almost certain that it did not break, but we are both really worried about pregnancy. It's both our first times having intercourse, and he says he felt a sort of pop when he first entered. Could that have just been my hymen breaking? He didn't really check the condom afterword, but there were no significant tears or apparent leaks coming from the condom. He didn't ejaculate, the only discharge in the condom was precum. Should I be worried about being pregnant?
