Oooh thanks for all your replies girls! They've been very enlightening - I am so clueless it didn't even occur to me that it wouldn't pop out!!

I would be happy with a flattened out/stretched version but from some of your experiences I might be waiting a while yet. I feel self conscious wearing tighter mat tops because you can see the 'crater' and it is not a good look It is starting to become less deep though so I will keep my fingers crossed.

Devon - I'll happily swap buttons with you now darl! It's always the way that you get what you don't want. I really hope your belly button returns to normal afterwards.

Puppies - I'm quite sure I've got an extra few kilos I could donate to you too I am certain you look gorgeous! I think it looks better when its all belly myself.
