I’m scared is this a kidney stone?

Have been urinating tea coloured pee for 3 days, I’m 23, went to do a kub X-ray, ultrasound, bloodwork, and urine sample test a day ago and waiting on the results, this just came out when I went to pee. My pee hole burns, not when I’m peeing but after. I’m peeing more and more often too. Is this a kidney stone.
