Bumped up to 100mg of Clomid

Well my first IUI was unsuccessful 😢, they had me on 50mg of Clomid and I didn't ovulate till CD 18-19. Started my period yesterday and yesterday's blood test was negative, plus they have upped my thyroid meds to 75mg, which is really scaring me that my meds need to be upped so frequently. Now I am to start on 100mg of Clomid tomorrow. I am going to try to get a referral for an endocrinologist to get a handle on my thyroid. Has anyone seen a change in their ovulation after upping to 100mg of Clomid? Anyone with hypothyroidism found success with stability and pregnancy?
