When there is blood in urine?

You need to make an appointment yourself then because you probably have a urinary tract infection. And, untreated urinary infections can climb up into your kidneys and cause permanent damage. Go to WebMd.com and type in urinary tract infections and read up on this condition. Lots and lots of water will help with your symptoms but, you need to get in to see a doctor soon. Pee into a cup and show your mother what color your urine is - then maybe she will take you ASAP. Otherwise, go to your school nurse tomorrow and ask for help there. She can intervene on your behalf.
