Possible PCOS?

Hi all, so I'm 16 years old and recently stopped taking my pill because I heard bad things about the pill I was on. I'm not sexually active so it isn't a big deal but being on here I've learned about my body, discharge, ovulating etc. So I stopped taking my pill in March and my periods were regular ever since I've been on time (28 day cycle) I've been seeing alot of changes to my body, but as I said I learned on glow and paid attention to when I was meant to ovulate. Unfortunatly, this being my 5th period I still haven't ovulated and this is stressing me. I'm not trying to concieve just a little worried that my body isn't functioning properly. Any help or advice will be much appreciated. Thank you!
