Scared I’m not ovulating?

I have fairly regular periods at about 32 days. Last month it was 41 days but I’m pretty sure I ovulated late and my period came in accordance with when I think I ovulated. I don’t use OPKs or temp because it stresses me out which throws my cycles off even more. I had a miscarriage in October but my cycles haven’t felt... right since then. I used to bleed occasionally when I ovulated (I haven’t since my miscarriage) and my periods always came like clockwork. My question is can I still have periods without ovulating? Is it ok to not bleed anymore when I ovulate? Am I suddenly infertile after my miscarriage did I develop Pcos or something? Was tested for all this before my miscarriage. I’m only 19
