YIKES! Potential pregnancy?

So at about 2am I am having sex with my ex. I flip over and he says “good thing you can’t get pregnant from pre-cum” when we’re done I attempt to push out anything that’s in me, he doesn’t actually finish in me though. But I wanted any pre-ejaculation- gone. When i get home around 1pm I sit down to pee and this egg-white(ish) long string plops out I to the toilet. I have never had discharge just fall out, some i’m wondering if it was the pre-ejaculation that I hadn’t gotten out prior? now... to add to this- I haven’t looked at my cycle/fertility predictions for the past week or two- so I didn’t realize I currently fertile and suppose to ovulate in around 2 says or so. Adding to that... I all of a sudden had a decent amount of water-like discharge and i’ve done a little bit of searching and i’ve seen it can be related to fertile discharge. So with this being said i’m just wanting some thoughts... not too sure where i’m going with this but I need some input 😅
