Lupron with IUI

Elizabeth • TTC #1 and it`s been 3 yrs. I`m 30 and my husband is 37
So my RE put me on Lupron 20 units for first 4 days of my cycle. Has anyone else done this? It's our first time using Lupron usually we've used Femera for the first 5 days of the cycle. This is our 5 <a href="https://glowing.com/glow-fertility-program">IUI</a> with unexplained infertility so it seems they are just trying different medicine. If you have done Lupron with <a href="https://glowing.com/glow-fertility-program">IUI</a> was it successful? Did you get crazy headaches?
