pregnant from pre-ejaculatory fluid??

I know it's possible to get pregnant from pre-ejaculatory fluid/pre-cum, and that it only takes one sperm to get pregnant, but do you think it's possible that prostate stimulation can somehow increase the amount of live sperm in pre-cum? I'm only around 6-7dpo and I'm pretty positive I had unprotected sex on the day I ovulated, but he didn't cum in me. I've been having a lot more CM than I normally do at this point in my cycle (and it's also really thick/lotion-like - something I've never experienced before) and I've had some light cramping (I never get cramps during any point in my cycle), I'm feeling extra moody/sensitive, and I've been constipated the past two days (maybe that could be the reason for the slight cramping but I really don't think so). I know the chances of me being pregnant are slim to none, and I won't know unless I take a test in a week or so, but do you think that prostate stimulation could have increased the chances even if only a fraction of a percent??
