How do you know?

How do you know if you have PCOS or endo? Or can you have both? As I continue my fertility journey I’m starting to wonder more about endo than PCOS or if they are intertwined. I have had a persistent cyst on left ovary, largest at 5.5 cm, but never multiple cysts. I’m ovulating based on blood work and nothing. No blocked tubes from doing an hsg and no scarring either. Could this be the cause?
