Confused and Upset

Looking for any type of support or insight. I have never not ovulated in a cycle usually ovulate cd 16 like clockwork. I do have slight DOR but thats never affected my ovulation and my FSH is at a good level. Last cycle I tried my first medicated IUI and we did leteozole. Quickly responded with one great follicle and did IUI on cd 13. This cycle we tried clomid for a more stimulated response. Went in for first scan no growth, they stair stepped me to 100 mg dose for 5 more days. Follicles still haven’t grown. What is going on? Idk what to even do at this point.
