Has anyone taken the fertility drug Letrozole???

Candice • My husband and I`ve been married 2 wonderful years and now trying to start our family.
My husband and I have been trying for two years with little luck. We have had two miscarriage's. Since then nothing has happened for us, so I went to see a specialist at the request of my OBGYN. The specialist said that everything was fine but since I have fibrocystic ovaries she thought this pill will help more than clomid treatments. Since I took them in the past and nothing helped. I was wondering if anyone has taken this before and if you had any success or if any one of you guys have any tricks that would help. Any suggestions would be great.
