Low dose Gonal >IUI >Progesterone cycle

Been on Gonal 50 iu since day 3. Today is cd9 and went in for blood and ultrasound. Only had 1, ONE!!!! viable follicle. Was 16.5mm today. Will go back tmrw or sat depending on bloods for trigger, then iui the following day. Feeling a little discouraged that I only produced 1. I had more with clomid!!!! Any words of encouragement.... Need all the positivity I can get.
