Bleeding during ovulation? Never happened before

Hi ladies.

I’m on cycle day 20 and the last day of my fertile window according to my apps and also as ovulation tests are coming up as next to nothing now.

I have noticed I’m bleeding which NEVER happens to me. I’ll include a picture but I’m so confused.

This is my first month trying and honestly we’ve only had sex twice but during my ovulation window. It’s too early for implantation so I’m not sure at all.

I never ever have bled between periods ever, not even during ovulation.
