Im 9 months preg and just gained 25 pounds how long until I get back to normal?

The weights pretty much all in my baby belly. I dont have fat anyplace else. How long will it take around for my stomach to be about 70-90% less fat and saggy? I am not going to be nursing :( I know that helps. I know it will be a long time before I get 6 pack abs if at all. I just wonder about what to expect thanks.
