Hello, on September 17 I was fooling around with my BF while rubbing his penis on my vagina without penetration or ejaculation while we were taking a shower,however he had some pre-cum on his penis and I was wondering if it is enough to get me pregnant giving that he urinated earlier that day.. Today is October 18 and my period is late 11 days, what are the chances that I'm pregnant? Please help.
