Trouble ovulating after miscarriage

I had a missed miscarriage and had a d&c procedure in July. After two cycles, I was given the all clear to start trying again. My doctor also had me start taking myoinositol since the d&c. This cycle I have not had a positive OPK. I came really close to a positive and it was still negative though. It was also later than usual. How long will it be until I start ovulating again? This makes me so depressed. I feel so sad and awful. I don’t think there’s anyway I could have ovulated this cycle. I wish I could be normal. 💔💔💔
