Ovulation after miscarriage?

Hi ladies, I had my assisted miscarriage about 5 weeks ago, my HCG levels returned to 0 about a week ago. I’ve been testing with my OPK for about 2.5 have not had a positive yet... in fact they have been pretty negative.

Any idea if I already missed my ovulation? Or if I won’t have one before my next cycle?

Just having a tough time lately and getting negative opk tests everyday is only making me feel worse.
