Very sorry this happened. That said a couple thoughts for the future.
#1 make sure you have a change of clothes with you always with this condition. Having had similar issues I can tell you life doesn't always make a bathroom handy
#2 what was your plan in very rough turbulence or take off or landing. Flight is sadly unpredictable. You may also want to consider some type of special underwear (hate to say it but diaper) for future flights
