Escalating Urine Issues

I am an 18 year old male. For about two months now, my urine has been much more foamier than usual. After about a week of it keeping up, I went to a doctor and had a urinalysis done, and everything came back fine on it. After worrying about it for a long time, I started to accept it recently, and assumed if anything were wrong with me, it would've came up on the urinalysis. This morning I woke up and urinated, and to my shock, my urine is now a deep orange color. I am also experiencing pain every once in a while in my testicles. My urine output has also decreased, as I usually urinate many (6, 7) times a day, today I have only urinated 4 times, two of those had VERY little output and were basically forced out by me, not prompted by my body. I have not changed my diet any lately, any one know what this likely is/could be?

Thank you very much.
