Last month on 2.5mg letrozole I had no mature follicles at my mid cycle ultrasound. I was devastated, especially since I had a follicle on the two previous rounds. I since switched to a new doctor who had me try 100mg clomid for this round. Ultrasound today and again no mature follicles. I’m so tired of having my hopes up every month just to be heartbroken. I think the next step is injectables like follistim but I’m terrified that even that won’t work. Anyone have a similar experience? Searching for some hope.
