Female ejaculate or CM?

So I usually get pretty wet when I'm fooling around with my SO but tonight it was to an extreme, I was riding him on top and when I was grinding you could literally hear/feel the juices gushing, it was like my normal wetness x 50, did I maybe squirt? Or was it just excessive CM? I'm currently 4dpo, and we BD'd on 3 days before and the day before expected ovulation (according to my apps). Could this be a good sign in the way of pregnancy or was it just likely REALLY GOOD sex?
