I had protected sex on the third day of my period since my flow was light. My only concern is that we used a condom that was in a wallet, and I've heard that it's not good to keep them in there. He only lasted about 5 minutes before he came. I'm getting paranoid however idk if I'm freaking out for no reason. We used a condom and nothing broke and I was on my period.  Can I be pregnant?
