PCOS help.

I have pcos. My doctor put me on letrozole because I got pregnant with my son while taking it (and following keto.) My follicle study for that round showed zero mature follicles and my cycle was 60+ days long. I gave up because I felt so defeated.

I started dieting again and I’ve lost 18 pounds in 2 months. Finally had a period after that long cycle. Now I’m on CD22. Negative ovulation tests. I got a TempDrop to track bbt, but I’ve only been using it for 2 nights. However my temps were 95.96 and 95.99. 🤷🏼‍♀️

Any insight or things I can do to help? I’ve tried inositol and haven’t had luck.
