Only ONE follicle IUI

Eve • Married. TTC 1st baby.

Took clomid 100mg 3-8 cd. Had my ultrasound today and only one follicle 20mm. They trigger shot me and have <a href="">IUI</a> tomorrow. Had anyone had good results with one follicle? Had anyone had this and following month had more follicles? Help! So sad and not optimistic about my chances.
