POSSIBLE PCOS ?

Hi girls I’m waiting to hear back from my Dr on blood results. Last month I had no period thinking I was pregnant but all test said negative ...went to dr she ordered blood test well just 2 days ago I started spotting pink/brown and today I started bleeding VERY heavily which ALL of this is out of the norm for me.. I’m so shocked why my body is doing this .. I did get jawline acne too which led me to believe I indeed hav PCOS ... I’ve had regular periods my whole life why now?... Im so impatient and just want to know what is going on with me ...any insight? Do you think it Is PCOS ?
