Spotting + Tender breasts at CD 14?

Just to be clear, I’m not pregnant or trying. There’s no way I’m pregnant. I’m a lesbian.

However earlier today when I went to the bathroom and wiped, there was a streak of red blood. Couldn’t have been from shaving because I haven’t shaved recently, or rough sex because we haven’t had sex in a few days and it wasn’t outstandingly rough. My breasts are also pretty tender, almost like PMS. Except I’m only on CD 14? I considered ovulation except my discharge doesn’t match up to ovulation discharge, it’s still thick. Is there anything that could cause this other than ovulation? Is it possible to ovulate with thick discharge?
