Birth control before IVFn

Husband and inhave been trying for over 2 years. I MC, endo and have tried 7 medicated cycles including 2 <a href="https://glowing.com/glow-fertility-program">IUI</a>'s. Since learning i only have a follicle reserve of 3 on each side ( was told 5-6 was normal) husband and i have decided to move to <a href="https://glowing.com/glow-fertility-program">IVF</a>. We were told by the dr that i first would need to be put on birth control... anyone else going through the <a href="https://glowing.com/glow-fertility-program">IVF</a> process been put on birth control before starting everything?
