Help!!

Is it possible to get a false opk peak/multiple peaks? I got a peak cycle day 17 so I would’ve “ovulated” cycle day 18 but my temps never spiked. They stayed between 97.2-97.4.

Well I kept taking my opks because I never did it a full month and I wanted to see what would happen...

well cycle day 28 comes (bbt 97.23) and that afternoon I get another peak reading. Well then cycle day 29 comes (bbt 97.46), cycle day 30 (bbt 97.41), cycle day 31 (bbt 97.61) — then I stopped taking my bbt because I figured I’d ovulated until 2 days ago when I started taking my bbt again because I missed my whole period and I got: cycle day 37 (bbt 98.04), cycle day 38 (bbt 98.00), cycle day 39/today (bbt 98.32).

I guess my question is did I really ovulate on my first peak reading or from my bbts I actually probably ovulated later around cycle day 29?

My cycles have been 26-30 day cycles the last 6 months. This has been the longest in a WHILE but still bfn so not sure how to calculate when I actually ovulated.

Please any insight would be wonderful!
