Hi Jeni!
Sorry to tell you that once diagnosed with PCOS, you will always have PCOS; it can go dormant and have recurring cycles etc.
Facial hair, cysts, discoloring of the skin, menstrual disruption, infertility etc are all partnered with PCOS. With weight loss these things 'usually' go dormant, but stress, birth control, pregnancy, miscarriage, stress etc can all cause it to flare up again.
Like the lady above said, there are skinny PCOSers too, It unfortuantely isn't a cookie cutter diagnosis, there is no one size fits all.
I hope your cyst issue is fixed up (was a month ago) somtimes bcp can help with ovarian cysts, but it sounds like yours has already gone past that point.
Good luck! (from a fellow PCOSer!)
