PCOS / OPK/ & Clomid

I am 35 and been TTC for 8 months! I have extremely irregular cycles from 12-49 days! I am currently being diagnosed for PCOS and possibly being put on Clomid.

I am also trying to establish the day of ovulation through clearblue advance.

What confused me on the high days is that they are 6 in a row without arrival of the Peak day - ovulation.

Does it arrive at all? I was under the impression that 4 days of High mean that Peak will follow around day 5/6?

Anyone in similar position with opk?

Anyone else any success with Clomid?

Thanks 🥰
