I'm feeling confused.

I went to the dr today for my mid cycle and she said the follicles still need to grow. The more I looked at the screen the more confused I became. I took a picture of it in hopes that someone could help explain, how big are my follicles and how big should they be? I'm not even positive I can tell how many I have. I think my anxiety is getting to me a little bit. Thanks for any help!
