Clomid vs progesterone

Jaqueline • 40y.o.- 4 failed IUIs-5th IUI ✔️-🤰🏻-👶🏻#1 3/12/21-2 failed IUIs-3rd IUI✔️-🤰🏻-👶🏻#2 2/2/24 🩷🩷👨‍👩‍👧‍👧

Was prescribed clomid because the only thing that they could find wrong with me is that my progesterone is low. So does that mean my ovulation is weak? If my progesterone is low why not just give me progesterone instead of clomid? Anyone out there with some insight on this?
