Don't worry about it, you can't even begin to compare bellies because there are so many attributing factors that determines how big or what shape it will be. At 34wks pg with my 4th baby I had a 130cm belly circumference! That's huge - and it got bigger too because I grew out of all my mat pants by the end LOL. What I wouldn't give to have a nice, neat and compact little baby belly

And don't dare try to compare to celeb bellies - celebs are usually so much smaller than normal people when they aren't pg - look at all the pics taken of Nicole Kidman - she looks like she is bloated and needs to have a big fart, not have a baby LMAO. And yesterday there was one of Erica Packer in the sunday telegraph, she is due in June and you wouldn't think she was any further along than 4mths.
