Okay I need help.

I have PCOS, had a period last cycle. First one in 2 months. Now I’m hurting extremely bad and feels like my cysts are coming again but like they’re trying to burst if that makes sense? I’ve had one burst so I know what it feels like. But any who, the more water I drink the worst it hurts. Then there’s fluid coming out. Like onto my underwear, feels like I peed myself. Idk it’s weird..
