uti? advice?

hi! i have high suspicion that i have a uti but don’t want to jump to conclusions.

here are my symptoms:

1. more frequent urge to urinate

- when i do only small amounts come out, and it burns slightly afterwards

2. minimal amount of blood when i wipe

3. slight discomfort in the pelvic/abdominal area

i’m 17 and i kind of feel uncomfortable talking about these types of things with my mom and always feel afraid to ask her to take me to the doctor for antibiotics or to get treated for something which is why i’m hesitant to say anything. but i also do not want to take this lightly because if a uti is left untreated it can spread throughout the body and cause bladder and kidney infections. yes, i am sexually active with my boyfriend but protection is always used. i didn’t urinate after sex the last time which i’m thinking is when i could’ve contracted this. please no judgement, i’m just trying to handle this situation in the correct way.
