I'm thirteen. When I was twelve I started this thing where every single time I laughed really hard I'd pee my pants. I still do. I'm good at hiding it and I'm too embaressed to tell my parents. I ignored it hoping it would go away on it's own. 2 Days ago I started to get this horrible cramp that felt like a period cramp. But it wasn't. My dad picked me up from my friends and when I got home I went to the bathroom. I kept having to pee and every time I went it was only a tiny tiny bit. It hurt really bad and burned and stung. It still does and when I wipe red orangish stuff comes off on the toilet paper that looks like blood. I only have to pee alot for like an hour, then if I relax and stop worrying I'll be okay until I go again. I looked it up online and theese are all bladder cancer symptoms. What is wrong with me?!
