Letrozole Experience Help!

I need your help! I am on my second round of letrozole TI, with a trigger shot.

1st round - I have a total of 4 follicles. The mature follicle was great at 23mm. I triggered in CD 12.

2nd round - I had my follicle scan yesterday and it showed several follicles. One was 12mm. And there were 2 dominate follicles at 19mm and 23mm. So we triggered.

Is triggering on CD 10 too early?
