Opk’s confusing me 😒

I got off the bcp about 3.5 weeks ago. I was diagnosed with PCOS when I was 16 and have been on it for over 10 years. I once went off for 3 months with no period. I am now TTC and i am so confused. How do i know if or when i will be ovulating? Or pregnant? Should i be not drinking etc. 24/7 as i dont know when or if my tww would be.. my husband and i have been having sex most days, and i have been taking clearblue advanced digital ovulation for 10 days - 1st day was solid circle no smiley, then i had flashing smileys for 9 days. Today i took a different test and it showed this:

For those with PCOS right off the pill how do i know my “cycle” or when i could be ovulating? Going to see a specialist in october she wants me to go on letrozole but is that a bit hasty?
