Just diagnosed with PCOS?

I went to the Dr. cause I was having irregular periods. While I was there he asked me how often I had a period (3-5/year) and then asked whether I had hair on my . (I don't) He then told me that due to the fact that I don't have hair on my that I have a very mild case of PCOS. However, I do have extra hair on my upper lip, chin, and under my belly on and he didn't even ask about this. He didn't really even tell me what PCOS was and what I know about it I have looked up online (which can be wrong) so I'm not sure if I know what Im talking about. Anywho, he put me on Aviane birth control and told me to come back in 3mos to check on B/C and have bloodwork done to be "actually diagnosed." While on this B/C I had some problems with it. I had sore that I couldn't even wear a bra for the whole 3mos, a headache the WHOLE TIME, and I had nose bleeds. When I told the Dr. about the nose bleeds he said I was imagining it cause he had never heard of it. But it clearly reads in the drug info packet he gave me that that is a serious side effect of this stuff. When I went back he simply switched the B/C and didn't do any blood work. He acted like he didn't know what I was talking about when I asked if he was going to do any blood work. I also have read that hair loss can be caused by PCOS-I have bald spots ... he says that its not though. So, I guess I want to know if I need blood work done or not. Are there any alternatives to B/C? And can PCOS cause hair loss like that?
