Follicle size ok for IUI??

MW

Went in for an ultrasound this morning (Friday) and I had two dominant follicles measuring at 11 and 13. Doctor wants me to trigger Sunday night at 11 pm and <a href="https://glowing.com/glow-fertility-program">IUI</a> at noon on Tuesday. I'm worried these follicle sizes are too small but I know she's the professional. What do you ladies think??
