Pcos definitive symptoms. These areas?

I have one concern do I have pcos ? I havent missed any cycle through out my life. Sometimes periods gets delayed by 1-5 days , usually my cycle is around 30 days.Once or twice in a year my period gets delayed by 14-15+ days. Then when it comes it happens naturally, My flow in one cycle last for 3-4 days. Also in june month j was taking placida and in july I took indreal la (both prescribed by doctor) Last cycle had less flow.currently im on my 2nd day of period. Does this indicate PCOS? Im kind of confused about facial hairs, I have one strand in my chin noticed last 3-4 years back , 2 noticeable strand one my chest . Since childhood Iike around 13/14 years I have hairs on my lower abdomen its in a straight pattern. And also since last many years i have noticed some hairs around my nipple area too Is this Pcos/pcod? I domt want to get unecessary tests What are definitive signs of pcos? Is this hair thing normal in these areas?
