I had protected sex with my boyfriend on friday (last day of my period) and saturday and today (sunday) my pee kinda burns.. and sometimes I feel like I need to pee really bad but when I use the bathroom it isnt alot. Whats happening

UPDATE: thanks so much i shouldve known it was a uti the girls in my family get them alot i think my issue was i didnt pee after we had sex or i wiped the wrong way my mom luckily has antibiotics for it cause i dont have insurance to go to the doctor right now if you guys have any remedies to help cure it quicker let me know
