[ ] Start complaining. "I'm so fat" ... "There's just no time to work out anymore "... You get the idea.

[ ] Hold off on the maternity clothes just a little longer... or at least find some cute ones.
[ ] Keep the "doctor's appointments" to a minimum. Try the old plumber/electrician/cable guy/whatever excuse instead.
