In need of help to understand follicle growth

Vanessa

Hello I am in need of advice.

I had an ultrasound on day 11 of my cycle but my follicles were only 9mm and endometrium was 6.9

Obviously my follicles are not big enough. I was told to go back on CD 15 to check for growth. Should I expect my follicles to grow at all or should I take it as this cycle will not work for us?

Thank you in advance for your help.
