So my girlfriend and I have had sex around 10 times. All 10 times we've used a condom, but this month she is convinced she is pregnant. She doesn't know for sure when her cycle is, but last night we had oral sex, and she said she experienced some spotting after when she was home... I always check the condoms to make sure they didn't break afterwards, but I once fingered her after I removed the condom, and she is sure that's when it happened. What do you think?
