PCOS?

My doctor told me my DHEA-sulfate levels were slightly elevated and said I have PCOS. I have no other symptoms of PCOS. I am feeling like they want to push clomid. I have regular periods and have never missed one. I also know I'm ovulating because I get positive ovulation tests. Has anyone had this hormone elevated? And by elevated it was at 339, which apparently for age range 20-29 this is normal but once you hit 30 normal is no more than 270? I'm 31 , seems this is right on the cusp...
