Vaginal tear? or UTI?

So a few days ago my boyfriend and i did the thing. It was rougher than usual and i noticed the faintest tint of blood on the toilet paper after. Two days later i had some pain during peeing. The pain is still here after about two days. I’ve asked some people and they say it might be a tear. I was wondering how long should i wait until it either heals or have to go get a test
