AMH levels

My AMH is a 6.71. The normal range said 1-9. However when I google is says higher than a 3 can mean PCOS. I have never had symptoms of this. I have super normal cycles and have my whole life. I’ve also had 2 ultrasounds to check my ovaries and no one has mentioned this.

My questions are... can I have pcos and not know? What were your AMH levels if you have pcos and did you conceive?

Thanks and baby dust!
