Go to the doctor right away. I know you want your siblings to get more christmas presents and what not but they will understand one day at least that you were sick and needed to see a doctor. Blood in urine is a bad sign that the infection in your urinaty tract has gotten really bad. That is what you have more likely since you have explained that it hurts when you pee and that you pee frequently. Good luck hope all goes well
hiya, me and my mum each get this a few times a year, sometimes bleeding with it, you should go to your doctor straight away, if you live in the uk, you will get your treatment free...and if you live in another country it won't be a lot of money for antibiotics which you will probably be prescribed with as it sounds like a water/bladder infection, don't put yourself through all the pain because it may get worse, my mum had it for as long as a month once, you need to get rid of the infection as soon as possible. also, i was told it could have been a kidney infection, and that's worse, so don't leave it, get it sorted. you wouldn't like your brothers or sisters to go through pain so that you could get something materialistic, you know?
