Help!?

Ok so I have PCOS and my periods are VERY irregular... So I haven't had a period the past 3 months, no spotting or anything just cramps and sometimes the pain is enough to bring me to my knees but the doctors told me (3 months ago, right after my last period) that everything seemed to be fine-- considering with the PCOS. But this morning I woke up and it's the same cramping but I had a slight brownish-pink discharge or spotting according to Google? I just don't know what's going on.. I'm not bleeding or having periods but I'm in constant pain and now spotting after 3 months of nothing. Has anyone else find through this?
