going off Spironolactone to diagnose PCOS?

Long story short, I had an appointment today with an OBGYN for a Pap smear/exam. I was told by my PCP that I should ask for an ultrasound due to my painful cramps and irregular periods. My OBGYN was wonderful and really helpful, however she basically said since I’m on spironolactone I would need to go off it for a period of time to get diagnosed with PCOS since you have to have 2 of 3 symptoms (testosterone levels, cysts/fibroids, irregular periods)…

Has anyone had this experience? I’m on 150mg of Spironolactone for severe acne and the thought of going off it really scares me. Just looking to see if anyone else had to do this. Luckily, she is going to proceed with an ultrasound first to see if I have fibroids but I’m worried that may be something I have to do in the future :-(

Thanks for any help :-)
