Uti help please! Spotting blood w UTI

Okay I’ve had UTIs before, today my UTI came out of nowhere & was so uncomfortable I had to leave work. At the clinic they tested my urine & confirmed the urine infection. They said to look out for spotting/bleeding which I understand. Finally felt relieved after some medication they gave me the first dose there. Well it wore off & im back to being so uncomfortable again. However this time I used the bathroom there was some blood spotting, very tiny amount on my toilet paper almost like little flakes off blood. Not sure if I should be alarmed? Advice please! Thanks
