Pregnant personal trainer body swap

I'm so glad they've invented this app to swap bodies so someone else can do your workout class for you when you want a day off, some days I just need to relax. Butttt today it has gone very wrong I've been swapped with a pregnant woman!!! I cant believe it, look at the size of me, my belly is HUGE! I try and find out what's happened, turns out it is a major problem with the app, they cant rectify it right away either, so you're telling me I'm stuck like this until you find out what the problem is?!
