Question about ovulation

Top is 3 hour hold at 4:00 pm

Bottom is 1.5-2 hour hold at 8:30 pm.

I feel like if I waited longer the bottom would have been positive? Glow is estimating I ovulate tomorrow. I think I might have ovulated today. Suggestions?

I’ll take another at 4:00 today too but I have a feeling it’s going to be the same or fainter.
