Experience with fertility injections?

Ch

Does anyone have any experience with follistim/Gonal-F paired with trigger shot?

I’ve done 4 medicated cycles with letrozole paired with trigger shot on 2 of those and progesterone supplements but no luck. My new fertility specialist wants to get more aggressive with injectable meds paired with IUI. Interested in success stories or stories of overcoming weaknesses. Definitely on a journey to try to become a level stronger with self-injections!
