PMS or PCOS

For last few weeks I have felt weird 
I have any of you had PMS like this:
Hot flashes 
Indigestion 
White discharge 
Headaches 
Bloating 
Acid reflex 
Weird sleeping patterns 
Dizziness (like you where on a roller coaster) 
A very light period 
I know your hormone levels are supposed to drop when your period finally starts but I still feel icky. I think I  might have PCOS
