so i had sex in the shower. two sessions . we finished , we washed up.. 2-3 hours later i went to the restroom and it burned so bad when i peed ... i had been on my period the last few days but stopped spotting today morning .. when i went to the restoom it burned and i also had peed blood. . ( did not look like period blood because my period usually includes blood cloths) i drank a water bottle .. throughout

the day i have been bleeding but no pain ..... what could this be ? hasnt happened before and I've had the same sex partner for 4 years .
