Letrozole Follicle Scan

Ha

Okay so I had my first follicle scan on CD 12 after taking letrozole and the tech said she didn’t think I was responding to the letrozole because none of my follicles were growing from what she could tell. I go back tomorrow on CD 15 to see if maybe they had a late start. Has this happened to anyone? Trying to stay positive that maybe it’s just taking a bit longer.
