Why is my CM watery?

Normally I only have variations of creamy cm all throughout my cycle (never have any EWCM) and is dry the week leading up to AF, but this time was a little different.

I had a heavy amount of thin milky type of cm on both ovulation day and the day after. I also BD on both of those days as well. On the 16th it was still heavy and milky then switched to being watery ever since then. So much so to where I thought that I either peed myself or that AF started early. It leaves a puddle in my underwear and is clear. I normally don’t ever have watery cm and heard that it’s supposed to come before ovulation not after.

Has anyone experienced this or may know what this is?
