Ovulation spotting - how much is too much

OK so my husband and I have unexplained infertility, have been two two clinics, etc. I'm no stranger to a bit of ovulation spotting but this month I've been spotting a LOT and it's starting to concern me.

My predicted ovulation day is today, I no longer tests because I know my cycles well at this stage. I know I typically ovulate a day or two earlier than the app.

I've been having EWCM mixed with blood since Saturday, and it's now Tuesday night. It seems to be getting heavier today, it's not dissimilar to my pre period spotting. Only with EWCM. Since Saturday it's just been pink and her and there, but tonight it's more red.

I am also cramping more than usual, but I know I am prone to cysts and maybe one is leaking?

I dunno. I don't see any doctors now because they've been unable to help so I'd need to try get in somewhere if it's a cause of concern. This is not a medicated cycle (I have been on Clomid previously) and I'm not taking any clinic prescribed supplements at the moment.
