Every month for the past 8 months I have been having UTI symptoms, very painful urinating and I never feel as if I have been able to fully relieve my bladder. I go to the dr and he gives me antibiotics. I am starting to get very worried that this may be something more serious, I get the pain directly after my period. This month it is way worse, I now passed a long clearish mucus and tissue that had streaks of blood. What is going on? I have had kidney stones about 7 times as a adult this does not seem to be the same, I am starting to wonder if this is even a UTI as well. What could it be?
