I was diagnosed with a uti a couple days ago. this morning i thought my cycle was complete. but just now i wiped and blood was on the tissue.

Common: It is not uncommon for a physical illness, like a UTI to affect your menstrual cycle, including the symptoms you describe. It should resolve on its own. However, it is important to differentiate vaginal spotting from gross blood in your urine. If blood in urine or if vaginal bleeding persists or worsens, see your clinician for further evaluation.
