follicle size

I just got back from my gynec appointment today. It was 2nd cycle on letrozole(5mg) I have 3 follicles in the right of size 1.4, 1.5 and 1.7 it was day 13 of my cycle. 
My doctor said I should not expect anything this cycle too( have been hearing the same for past 3 cycles) my first doctor had asked me to come back the next day to see if the size increases and it did increase but this doctor just straight away said not to expect. 
I just feel so hopeless hearing this. 
Is it the same for all I mean do u all have 2.0 cm follicle on day 13?
