Cd 12 follicle scan

Carolaine

I took 5mg of letrozole cd3-5 and went for my first follicle scan CD 9 which I had one dominant follicle of 10mm on my right side and many less than 9mm on my left (I also have pcos), my linning was 3.9mm. Today I went again CD 12 and my right side follicle didn’t grow at all still 10mm and now I have one dominant on my left side 11 to 12 mm and my linning was 4.1mm. Should I lose hope? Did anyone have something similar and they were able to trigger?
