Fat tummy

I know I'm getting a baby bump at 13w2d. BUT I already have the fat pooch that I didn't lose from 2 previous pregnancies and c-sections. Really hoping I can lose it this time around.....but I have zero motivation!!! 3 babies in just a little over 3 years will take a toll on a body. Especially with c-sections. Thinking this is the last one. Don't know if I want to have another c-section. 3 seems like enough.
