uti... BUT SOMETHING ELSE TOO??!!

okay so I have a UTI at the moment. It sucks . I’ve been to the doctor already and I’ve been taking antibiotics for about 4 days now.

i masturbated yesterday, I used my fingers first . Everything was fine, then i switched to a toy that I have and when I was done , I pulled it out and there was blood😭 I didn’t see any blood when I was using my fingers though, so I have no idea what’s going on . I don’t believe i scratched myself or anything with the toy either . I peed afterward , there was a little blood when I peed but not much . Then I went to bed.

This morning I got up and there was brownish blood in my underwear. I’m not on my period, because I just got off my period last week .

What could this be ?? Is it because of the UTI??

This has happened only one other time ( 6+ months ago) HELP!
