Discharge before period? Normal?

I can’t remember ever having this before. My period is due within the next couple days and today, I had cloudy, liquid-y discharge at 12 days post ovulation. It was the color of milk, almost. I know for a fact I ovulated at some point, because I had egg-white cervical mucus and pain on my right side during that window. Could I have predicted wrong? I’m just a little worried because I had protected sex on the 14th, but I probably should be okay, hopefully.

Normal?
