What Is The Treatment For PCOS?

hi my name is Samantha Claybon and I am 19years old. I have recently been diagnosed with POS. I Have not been havibg my period. I have been noticing that I have brownish discharge, and I constantly have to wear a panty linner. My othe concern is that on Sat. I had sex and when i went to the bathroom I noticed that I bled through my underwear and my pants. This is weird because I am not a virgin. It has been 3 days since then and I am still bleeding heavily like I'm back on my period. Please Help Me
