Ttc- no ovulation after Hsg

I recently had an HSG done about 3 days before my fertile window

I heard the next couple of months after having hsg done you are the most fertile, so many women have gotten BFP’s that cycle.

I met with my doctor and everything was “normal” and couldn’t get prescribed clomid because I had a dominant follicle at a previous US appt. now I’m left with no options, my husband and I have been TTC for about 2 years

I was referred to an RE but I just don’t know what to believe or how to handle still having no answers

On top of all this, per OPKs, I did not ovulate?? I just don’t understand... anyone else go through something similar? Advice?
