EWCM three days after LH surge?

[Rosslyn]

Hello, all. This is our first month trying. I took an OPK on Sunday night and it was positive. We were not able to try until last night but I kept checking my CM and didn't get EWCM so we used preseed yesterday. This morning when I wiped there was EWCM and it seemed real, not like the texture of the preseed. Is it possible I ovulated yesterday? Or is it more likely that the CAM took it's time working it's way out? I've been all set thinking we got too late and this month was a wash.
