from blood to slime?!

Billie

I have Addison's disease and recently recieved an emotional shock. Since then my period suddenly went from being easily poured out of my cup to having to be scooped out. Its slimey and leaves long trails (like moccerella) so i have to be very careful removing my cup for any not to get down my leg or on the floor. And when it sinks to the bottom of the toilet it doesnt flush away. It sticks and i have to use the toilet brush to remove it. Its extremely frustrating. Im 33 and ive never had periods like this. In also hoping to try for a baby soon. Concerned this sudden change in my uterus could be a sign of something bad?
