Hi Owen,
Welcome to BellyBelly - this is a great place.

Yes - I've been undoing the buttons pretty much from the 5th week and its definitely a bigger belly by nightfall LOL.

On the doctor thing - it is amazing how ignorant some members of the medical profession can be about the most ordinary symptoms of pregnancy!

If you get a chance go and check out the Belly Buddies Threads and introduce yourself to your belly buddies (ie the gals that are due in the same fortnight as you!).
