Iui with only 1 mature follicle

Wendy • Expecting baby #1 11/8 after ttc for four years
I have back to back <a href="https://glowing.com/glow-fertility-program">iui</a> scheduled for Friday and Saturday. I am doing a trigger shot tomorrow night. I have one mature follicle at 19. Should I proceed or wait for another month with more follicles? Any advice would be appreciated!
