Hey all, a couple weeks ago around the 10th of February my girlfriend and I fooled around a bit. Not to be graphic but this is necessary. I came in her mouth, she sucked most of it off and swallowed, I then went and peed. After that I came back and barely rubbed my penis on her vagina. She told me she had a light period this month, but also had a light period last month (we didn't fool around last month at all). What are the chances she's pregnant?
