Clomid not working

We have been TTC for 13 months. I'm December started clomid and had HSG. Husband tested and as far as labs go we are normal. As far as periods go I hardly ever get them so I take progesterone every month. This is our second month of the clomid and this is the first time I never ovulated! Dr. Wants to try upping dose and maybe checking with ultrasound before doing <a href="https://glowing.com/glow-fertility-program">IUI</a> next month. Wondering if anyone out there had similar issues. Thanks!
