What's going on?!?!

Monica
Hubby and I did the deed either Friday evening or Saturday evening and I had a glob of ewcm hanging out yeaterday (Monday) bc of my small frame (I'm guessing) I've never really experienced the ewcm this was my first time. Today my cm is more wateryish does this mean I ovulated Monday? And if so does having sex 2-3 days before ovulation increase your chance of getting pregnant??
