Hmm, I've been swimming in the TWW before. It doesn't worry me much. It probably doesn't take long for the mucus to form back where it was after an IUI if I'm to guess. It probably would be best not to in the first couple days after the IUI, but you're further out than that. I'd say, have fun!
But if you're worried and think you may end up playing the what-if game in your head, don't go. This is all my unprofessional opinion, though. Maybe it's best answered by your doctor.
