First of all congrats on getting a proper diagnosis. I have PCOS as well, but all my hormonal blood tests ALWAYS came out normal, except for the fasting blood sugar.
So regular OB_GYN never diagnosed me, only when I saw a specialist did she diagnose PCOS on the basis of the blood sugar levels. So you are definitely not alone in this situation.
I would advise you not to take birth control pills unless you absolutely have to. If you are concerned about not getting pregnant, use condoms.
Your fasting blood sugar of 126 is in the lower limit of a diabetes diagnosis (A healthy fasting glucose level is between 70-90, but up to 110 is within normal limits. A level of 111-125 indicates impaired glucose tolerance/insulin resistance. A fasting level of 126+ indicates type II diabetes.).
To bring the blood sugars under control, you need to excercise and modify your diet to reduce carbs and increase protein. Also, a loss of 10% of your body weight is helpful in bringing down blood sugars, and can even cure you of the pcos symptoms. This is what the diabetes specialist will also tell you. See a dietician if you can to help you plan proper meals.
One thing that is extremely helpful in reducing fasting blood sugars is to eat an early dinner, and then have a small snack right before going to sleep. Also, when you see the diabetes specialist, they will probably give you a blood sugar monitor that you can use to keep track of your fasting blood sugar, as well as your post meal sugars. This has helped me a lot in figuring out what foods work for me and what don't. And it's not painful at all!
If you don't control your blood sugars, and get pregnant, you are at higher risk for miscarriages and birth defects, which is why it is TERRIBLY IMPORTANT to bring them under control. My doc put me on a medicine called Metformin, which is basically a diabetes medication. But what helped me most was walking 20 minutes after each meal and also eating less rice/chappatis and more protein. This regimen works wonders in controlling your blood sugars.
Your testosterone levels are not too elevated. Check this website -

Also have your doc perform the test called hb-aic test, which measures the average blood sugar over a period of 3 mos. If the value for this test is over 6, you are at greater risk of pcos complications. See the site
The HbA1c Story
But dont worry too much. If you follow a proper diet and excercise plan, you can reduce your blood sugars without having to resort to medications. I am living proof that this is definitely something that you can control and conquer! But you will need to devote time and effort to maintain a healthier lifestyle, which is anyways, good for you and your family in the long run!
Cheers!
