Did I miss ovulation?

I ordered ovulation tests as I am coming off birth control soon and will begin TTC. I hit what would be around the time of what I think was ovulation, and started having cramps and back pain (I’ve had it before during ovulation time). But I don’t know for sure if that pain was for sure ovulation.

The pain was on Friday/Saturday morning.

The ovulation tests were delivered Saturday afternoon, so when I got home Saturday night, at 11 pm, I took a test.

Top is Saturday at 11 pm. (CD 14)

Middle is Sunday morning. (CD 15)

Bottom is Sunday afternoon.

I just want to know if maybe I ovulated Friday or Saturday morning, based off of these tests because they’re getting lighter. Thoughts?
