I'm so sorry you're dealing with that and have to take antibiotics again. There can be a connection between IBS and bladder problems, we have an article about it here: https://irritablebowelsyndrome.net/clinical/bladder-problems. However, I'm not sure if there's a link between just a normal UTI and IBS. I know people who get those very often, but they don't have IBS... Has this happened to you before, or is it just this one time?
I hope it'll just pass quickly and you won't get it again.
Wishing you all the best, Karina (team member)
