freaky things happening and need explanation!

Rory
So a couple days ago I started feeling really really bad and it progressed throughout the morning. I had intense heat flashes and abdominal pain and overall fatigue, and then I started getting TONS of this weird rusty discharge and overnight it turned to blood. I wouldn't think this was weird normally because it sounds just like a normal period, but this was 10 days after my last one, and it was super super intense and painful. It also produced pains that I don't usually get from my periods. I lost an incredible amount of blood overnight and I'm freaking out a little trying to figure out what this could be. If anyone has any ideas please help me out!!! Xoxoxoxo🌸🌺🌺
