Follicle count

Hi,

I had an internal ultrasound and the tech said I have 20 follicle on my left ovary and 3 on my right. They did blood work as well to check for PCOS and it’s all within normal limits. The doctor said it all looks good but everything I read says if you have over a certain amount of follicles it means pcos. I’m so confused, am I being misdiagnosed? I get a period every 28-36 days.
