My PCOS symptoms recurred even with Spironolactone. Why?

Hello doctor,

I have PCOS whose symptoms are extremely effectively managed by both my oral contraceptive (Sprintec), and miracle drug Spironolactone, which I take 100 mg a day for. It has greatly lessened my period pain, cleared my skin, hirsutism, and kept my ovaries safe for around four years now. Now I have perfect skin and extremely regular periods, which I am very grateful for. After my period ended last week, within the past few days, all of my symptoms have suddenly returned, as if I never took the Spironolactone at all. I am afraid that either the medication randomly stopped working, or there is a deeper hormonal issue present that is overpowering its effects. I am also worried about the reproductive consequences of not taking care of this properly. My questions are have you ever heard of Spironolactone suddenly not working out of nowhere? What medications can I take instead of Spironolactone that can also target my PCOS and extreme hormonal cystic acne? If there seems to be another hormonal issue present, what blood work would you order?
