What kind of discharge is this? Am I preggers?

Boyfriend stuck it in me only once (did not come at all) on 07/09 (period was on 07/01-07/05), but I grinded against him for a bit (not clothed and no penetration). He did not come at all that day, and he peed at least 5 times while I was with him. I’m still worried a little bit about precum. My boobs have been sore for the past week, and I’m getting some cramps here and there. Had literally almost no discharge for the past week (creamy/sticky/dry) but here we are. Could this be pregnancy discharge, or is it unlikely. I’m pretty sure I already ovulated already, so why am I getting ?stretchy? discharge? Correct me if I’m wrong please !!
