I'm a 32 year old women that is married for the 3rd time & have no children of my own.

I started urinating blood last night. I already have MS & the only thing that I can think of is, NOW WHAT?

What could cause me to start to urinate blood everytime I go to the bathroom? Can someone please explain to me what could possibly be going on I'm honestly scared to death that it's going to be something major..
