Hello,

My girlfriend and I are concerned. We had protected sex on October 30, which was about 4 days before she started her period. I used a condom and it did not break and the pull out method. We had sex last Saturday, November 6 (the last day of her period). I used multiple condoms so there might have been a chance for a little cum, but I know it's too early for that. She said that she had light pink spotting on Saturday night and Sunday after we had sex. My question is, could this be implantation bleeding from Oct. 30, even if everything went well with protection? From what I have researched, it seems like it's just from rigorous sex, or from her period but we are still concerned. Any help would be great!
