Suggestions for temping?

Jasmine • Jasmine, 36. Mother of 2 & pregnant with #3. My baby girl 💞

I wake up a different times during the night so it's hard to know if I've gotten 3 consecutive hours. I don't always fall asleep at the same time either so I'm just gonna use opks. With my temps being off I think glow miscalculated my ovulation. Suggestions?
