Hello, and welcome to the forum.
Contracting a UTI either during or after the cleanse is not something that normally happens with people who are treating Candida.
You seem to be sure that it is indeed a UTI, so in that case I’m sure all will concur that you should see a doctor to be certain and to seek treatment if needed.
Before I would offer any suggestions for a natural aid for the UTI, I would have to ask if you are pregnant, and regardless of whether you are or not, I would still tell you to seek a doctor’s advice.
Please continue to let us know how you’re doing.
