What blood tests did they do? Did they do a full hormone panel, or just a few? If you aren't sure, I would call them and ask, or make another appointment to see. My sister's first doctor only checked a couple of things, and told her that she did not have PCOS. She read my PCOS: The Hidden Epidemic book and wasn't convinced, so she went to an Endo and found out that she was not only PCOS, but also Diabetic. Did they do an ultrasound or feel your ovaries?
Read this page linked below, and it will tell you the tests needed to diagnose PCOS, and what levels the results should be. I would call my doctor back!

The Gluc is a very good idea. You need it to get everything in line and help hold off diabetes. My sister went to a diabetic workshop at the hospital and they told her that insulin resistant blood was like syrup and it made the heart work harder to pump. That is an excellent reason for taking your medication and eating right. Here is some info on diabetes and insulin resistance. I know you are not diabetic, but it is important to see what CAN happen if the insulin resistance progresses.
