When to expect ovulation. Both normal.

Hello doctor. My period cycle is 32-35 days. I had period on 16 may'23 then in june i missed my period. So i took several urine pregnancy test which were negative. Then i went to my doctor in first week of july and she told me to get bhcg and ultrasound done. Bhcg was negative but ultrasound diagonsed me with pcos.. And my endometrial thickness was 15 mm so my doc gave me meprate 10 mg for 5 days to help me get my periods. So after 3 days of completing my course i got bleeding on 16 july which was of 5 days ( 16 july to 20 july ) . And the day i got to know about my pcos problem i am taking healthy diet and started exercising, as we want to plan for pregnancy. So my question is when will my next period start and also should i first treat my pcos and then should plan pregnancy.. also she ordered me to get other bloodtests done that is Tsh and prolactin which were both normal.
