thats not good you probably have a urinary tract infection.
go to doctor and they will do a urinalysis

You don't say your gender but if male definitely bad and need to see an urologist asap, it could be a bad urinary tract infection, kidney stone, tumor, kidney or bladder injury, etc. If female it could all of the above or as simple as having your period.
