burns inside, feel like peeing all the time and it burns when i do? was it ?

ive been drinking cranberry juice thinking that its an UTI and also been taking medicine for it for a day already but the symptoms are still there.. the pain started right after i had in a different position but i'm not sure what is wrong with me. i dont want to go to the doctor yet, but its been 5days. could my partner have hurt me? bc the irritation is coming from inside. we had unprotected and used a lubricant
