My boyfriend and I were messing around and he came a lot so I helped him wipe it off with a paper towel and after that I began to touch myself. Since then I had been off of my period for a week and 4 days later I started spotting, I have only had a few cramps, but I'm thinking maybe when I touched myself some of his semen got on my finger. There has been times where I have spotted before after having my period but this is too coincidental. Please help!
