Did I already ovulate?

Hey ladies! So I just finished my first period since my back to back miscarriages in December/early January. I had a very close to positive opk yesterday and the only reason I tested was because I felt left sided pain and my normal ovulation cramping. I tested again this am and it’s definitely negative. Is it possible to even ovulate that early? Or was it just a fluctuation!? Please share your thoughts as I’m faithfully a CD 15 ovulater!

Yesterday am

This mornings!

Thoughts?
