I am sexually active. Diabetes runs in my family, as well as cancer . I have hypothyroidism and take pills for it. I am 18 years old. There is a burning sensation in my lower abdomen, right above my pubic bone after I urinate, and there are sometimes also small red/orange clots. I am pretty sure it is a UTI , but are these clots a sign of a kidney issue? Or something else... And how soon should I see a doctor before it gets too serious? This has been going on for 2 days.
