First IUI

We are having our first <a href="https://glowing.com/glow-fertility-program">IUI</a> in April. My husband has low morphology (21%) and the doctor wants him to take fertilaid for 2 months before we do it. I don’t have any issues (regular periods, ovulate every month, no blockages) but is it normal that they put me on medications too? Femara? And ovirel? What happens if I ovulate in my own before the trigger?
