Ovulation bleeding? TMI PICTURE.

Jaimee
Positive opk on the 12th. Fertility friend confirmed o on the 11th, and glow says the 13th. 
Well I just went to the bathroom. It's 11pm in my area, and there's pink spotting. Barely enough to really even tell. Would this be bleeding from ovulation? When does ovulation bleeding even happen. 
My heart literally sank when I saw the spotting on my toilet paper and immediately I feel like I'm broken. :/ 
Any insight would be wonderful.
