Watery discharge- sign of ovulation in cd30?

Yesterday I had a ridiculous amount of watery discharge. Like, my undies were wet, it looked like I had peed my pants. No odor.

I’m supposed to start any day now, so far no symptoms.

I know discharge has nothing to do with pregnancy (or being able to tell if I am or not), but I’m curious if anyone knows why this happened/happens?

My husband and I haven’t had sex for a few days, so nothing left over. And I normally ovulate between day 14 and 21. I’ve stopped tracking for ovulation, but I am tracking my cycle days and this was day 30...could it have been a sign of ovulation?

Or just something weird that happens? Lol
