Baseline Ultrasound and cancel IUI

Fertility IG: Jazmin_lvv

I had my baseline ultrasound this morning and I have a 2mm cyst on my right ovary and 3 follicles. My doctor cancel my IUI this cycle I am so frustrated because this is my 2 cancel IUI back to back. I can’t catch a break but also why do I only have 3 follicles why can’t my body produce more I am 30 years old ?
