is this a possible uti comeback?

i had a uti around december time and got antibiotics for it, now i woke up and have the constant urge to pee, small amounts come out and when they do it stings and burns. i assume it is another uti except i cannot take antibiotics for it again since i took some for my sore throat about two weeks ago and got an allergic reaction to it. nothing serious but the doctor said it could be caused by the antibiotics. anyway point is i have no idea why i got a uti again since th first one i’ve been wiping the right way peeing after sex and trying to do everything “correctly” or as prevention yeti think i got it again. i know it’s common but i don’t want to take antibiotics again. do you know any home remedies? all i heard is drink lots of water(?)
