How long did it take you to get back into shape with no. 2

I bounced back after no. 1 ... Not happening with this one. I feel so fat and disgusting. Nothing fits and my post baby body is flabby and gross. I am in the fitness industry and have 14 weeks from now to get back into shape... I am currently a size 14 and am normally a size 8 ;-( I feel like I have a huge mountain to climb to reclaim some of my former figure.
