Very confused...

Alisia

So according to my app I’m ovulating but this morning when I woke up and went pee there was blood. Not like a whole lot and not bright red either so I know it can’t be my period. I didn’t have sex last night either so it’s not like I got torn. It was like a light spot nothing was on my sheets or underwear and I doubt that it’s implantation bleeding cuz it’s rare for that to happen. Has anyone else had this issue or what could it mean?
