Pretty sure I have PCOS

Can someone tell me if this sounds right...

-I have irregular periods (I go months without one)

-I have facial hair (black chin and upper lip hairs that I pluck/wax constantly)

-Overweight

-Lower sex drive

-When I DO get my period, it’s very heavy & lasts at least 10 days

I feel like I have PCOS, if I go to the doctors, what do I tell them? Do I have to suggest PCOS? What are the tests to see if I have it? Any advice or suggestions
