Help With My UTI

So I’ve been having unprotected sex with my boyfriend and I apparently caught a UTI. My pee has a foul lighted smell & previously it was really hard for me to get all my pee out at once . I went to the doctors and got checked and they said I don’t have a UTI and everything is cleared but this was a while back . But I think I do so can you guys give me ideas / home remedies to get rid of this UTI.
