pee smells but no uti ???

i got tested for a uti and it came back negative, i haven’t had pain when peeing or urge to pee. but i notice my pee smells fouler like when i’ve gotten a uti in the past. i drink water and sometimes my pee is even very light yellow but still smells a bit. it’s been going on for almost two weeks. any causes for this and has anyone else had this issue ? thanks!
