I started finding blood in my urine about 2 weeks ago. At first it burned and show alot of blood. There is a considerable amount of pain in my lower back and abdomin that comes and goes. There is also some kind of mucus in my urine. It usually is accompanied with great pain. It will actually stop the flow of urine, like it is blocking it. This mucus reminds me of veins one finds in cooked chicken. Over the last two days my abdomin has bloated slightly causing all of my pants to become uncomfortable. Last night I actually lost control of my bladder and wet myself. This is all becoming very stressful since I cannot afford a doctor visit. I know that I am not pregnant and would like to know if this is a uti or something worse.
