It sounds like what you are describing is a lot like what I am going through. My doctor diagnosed me with PCOS, but a year or two ago, the cysts mysteriously vanished and I no longer have PCOS. I would get in to the gynocologist and have your hormones checked again. Since you are dieting and losing weight, it may not be a bad idea anyway. I have most of the symptoms you do and was diagnosed with PCOS without having PCOS. *Shrugs* Or, maybe we just produce more testosterone and prolactin than most women. I also started my period very young (10yrs.) so who knows? Did you recently come off of the pill? Because that will do it too. Though, you would more than likely have irregular periods if that were the case. Trust me, I would know. See a doctor. What harm could it do?
i also want to add i have no thinning of the hair on my head, no skin tags or any other visual symptoms of the disorder except the body hair problem...
