Possible uneducated question about ovulation

Sorry if this is the stupidest question on earth.

So I know about LH surges and ovulation and the egg being viable for up to two days after its released and such, but I just want some clarity on cervical mucus if I may.

Watery discharge is leading up to ovulation. EWCM is when you're at your peak. Am I right in saying once the egg has been released, the CM dried up? Or is that only after the egg has been dissolved?

My predicated ovulation day is tomorrow but I suspected I ovulated yesterday (I ran out of tests), because today I have no CM. I did BD on Tuesday night, I just want to know if it's worth doing it tonight too.

Thanks ladies, I'll just ask my gynae next time I see her. Thank you for your answers but they don't actually answer the question.
