After having children (youngest is 18 so some time ago) I did my pelvic floor exercises like anyone else and never had any problem. Maybe needed to concentrate a bit more when bouncing on a trampoline or (sometimes) when about to sneeze but that was it.
Twice recently I have been travelling home in the evening and found that I have wet myself en route. Nothing dramatic, haven't felt any sudden loss of control, just found that my underwear and trousers were wet when I got home. Eg last time had been to an evening meeting, drank one cup of coffee and a couple of glasses of water but felt no need to go to the loo before setting off on the 40min tube journey home and no discomfort whilst I was travelling. Got home to find my pants and trousers wet.
Obviously not happy about this. Why would this be happening? Restarting pelvic floor exercises is a no brainer but should I be thinking of anything else? Any why would it happen sometimes but not others?
