chocolatey brown discharge? no period for almost two months?

okay so firstly i’m going to introduce the fact that i might have PCOS but i havent been properly tested as i’m very scared of needles.

i never had my period last month, done a pregnancy test and it was negative. this is okay as i skip periods because of PCOS.

this month, so far ive had no period however yesterday and today ive had a lot of chocolatey brown discharge. also today ive had a really sore feeling in my stomach, kinda the feeling you get the day after youve worked out. its really painful when i move or bend over.

What does this mean?
