Crampy and milky cm? TMI

I'm 4 months PP from a second c section, cycles have been regular but having problems with my period itself, so I'm not on any birth control right now, only using condoms.

So this app is predicting ovulation tomorrow, I know the app isn't 100%, but this cycle I'm experiencing something weird, I'm really crampy, like my uterus just feels sensitive, even to moving around, coughing, laughing or whatever, and I keep feeling leaks, like you'd expect when you're on your period and feel the blood, but instead it's white and milky, like alot of it, enough to soak my underwear.

Is this all normal during ovulation week? I've never experienced this before.

Also not sure if this is connected but my c section scar is feeling extra sensitive and achy when I don't usually feel anything there anymore.
