Follicles

So just had my ultrasound to check my follicles and it looks like I have four ranging between 14 and 20. My question is what do y'all think is the optimal size before triggering with the shot? I had four last month with one being 28 and the others in the low 20s. I only take clomid. The first month I took Gonal F and it made me have 9 plus follies so they wouldn't do the iui and told me not to do those shots. So 3rd time here but only 2nd iui! Super nervous about what is good as far as size goes. What do y'all think?
