Please help me! I'm 13 and my pee smells bad and I wet my bed?!?

I'm a 13 year old girl and I have started my period. For about a week or two, my pee smells really strongly and it is very dark yellow. I am also having greenish white, smelly discharge. But just last night I wet my bed for the first time since I was like 2! It wasn't just a little bit. My underwear, my pajama pants, and my sheets were soaked. I went to the bathroom before I went to bed. I have noticed that I have been peeing a lot more than usual lately. I normally pee about 2-3 times a day but in the last week, I've had to go 6+ times per day. What is wrong with me?! Please help me!
