Letrozole and PCOS

Whitney • 25, Married, RN, TTC #1 with PCOS, IVF warrior- 2 failed FETs

I’m getting ready to start my very first round of Letrozole as soon as AF shows in the next week or so... I’m nervous as this will be my first infertility medication and this whole process has been pretty tough for me emotionally. Does anybody have success stories from using Letrozole?? My Dr wants me taking 5 mg on days 3-7. I do have PCOS and my cycles are normally anywhere from 30-50 days, currently on CD 37.
