I feel your pain, mate. I have been trying really hard the last couple of months to shift my extra weight and have just about gotten back to pre-pg weight... but this belly is still there! And covered in stretch marks that are still bright red just to add insult to injury.
It is hard. But we'll get there. And a little belly is ok, IMO... reminds us of where we've been and the wonderful things we've accomplished! (But it needs to be LITTLER than this... LOL!)
