Confused

Natalie
Pretty sure I'm out this month. I'm so confused. Glow first predicted AF coming today. I was doing ovulation tests around the time I should've ovulated, all negatives. A week ago today I got a positive- cd 22. Yesterday I started spotting pink/ brown. This morning it's much heavier so I'm thinking its AF early but I just am really confused if I ovulated a week Ago?? We bd'd a lot around that time. Is there still a chance I could be pregnant at all? Does anyone have experience with this?
