Peak opk results for 11 days

Cayci

I have had peak results for 11 days and I'm so confused. Could my body just not be ovulating? Maybe it's trying and failing?

My cycles are irregular and long, lasting up to 50 days at its longest. I've tried tracking BBT but no raise thus far. CM has changed but varies daily between extremely dry and then medium watery.

I have been tested 3 times for PCOS with negative results.

Any advice would be great!
