combining Clomid and IUI

Elsa. • 25 years young, TTC for over 2 years now
Any success on combining these two? What days did you ladies take clomid and what days did you ovulate? I'm doing my first <a href="https://glowing.com/glow-fertility-program">IUi</a> in Mexico on Jan 11th so I'm not sure when I should take clomid? Any suggestions or advice?
