Confused with my cycle!

Brooke

I have PCOS and never ovulate on my own. I’ve went almost a year without a cycle. So because my husband and I are serious about getting pregnant, I started my first round this month of letrozole 2.5 mg once a day. I had ultrasound done on CD 12 and doctor said medicine didn’t work and he would bump me up next month. I’m now on CD 16 and I have this come out. Wtf is happening?
