Hey there!
Perhaps asking about other BCPs with anti-androgenic properties would be a good idea in order to relieve some of your symptoms. I too suffer from the classic symptoms of PCOS but have seen slight results after just one month of being on Yasmin and remain hopeful.
A friend and classmate (w/ PCOS) has been on Met and Spironolactone for a little over a year and has noticed a definite difference in the growth of excess hair and a reduction in acne. Personally, I plan to ask my doctor about Spiro because my friend has been so pleased with the results. The only problem is that it is a potassium-sparing diuretic, meaning it causes you to urinate more frequently but it causes the kidney to hold on to potassium. An excessive potassium intake can lead to kidney problems, but if you avoid potassium-rich foods these negative effects are unlikely.
Insulin-resistance is another important thing to discuss with your doctor, particularly if there is a history of type II Diabetes in your family. Furthermore, diet and exercise should also be addressed. Talking with a dietician might help with this as they might have great suggestions as of ways to lower your cholesterol or just help you maintain a healthy lifestyle in general. Oatmeal, for instance, has been known to lower cholesterol, and if your level isn't high enough to warrant medication, this more "natural" rememdy is something you might benefit from.
Nizoral, a perscription shampoo with 2% Ketoconozole, has helped reduce the amount of hair I lose each day and it has also made my hair less fine. This is something else you might want to inquire about especially if hair loss is a big concern.
Finally, I would just like to say that YOU ARE YOUR BEST ADVOCATE

, especially when it comes to your healthcare. The BEST way to arm yourself is to read as much as you can about what you have and how to treat it. One of the greatest things about this site is that you can read about what other women have tried in terms of meds, acne treatment, combatting hair loss, and good ways to remove unwanted hair. Maybe googling some of these things or going to the manufacturer's website could yield some interesting information and help you come up with more questions for your doctor. Be sure to ask your doctor about the side effects of any medication they recommend, and be sure you feel confident that the treatment option you and your doctor choose is right for you.
Sorry this is lengthy.

Hope it helps!
