Hi I'm 21 suffering from pcos... been to a guynae... not much help... I haven't had my period in 3 months... now when I discharge it has a slight pinkish and sometimes tinge of brown... for the last 3 days... I'm not pregnant... and I cannot lose weight... please help, my stomach is hard and severe pain...

I think this might be more than just PCOS. I would talk to your doctor or go to an ER.
