Brooking all goes wonderfully for you today Scream! Try not to be nervous - and I'm sure that your symptoms will start improving instantly after the CS, even if it takes a little while to be completely back to normal. Also, good point that Biscuits about birthday twins...
Scarlet, rubbish news about your MW's concerns :( Equally rubbish that they can't get you in for a scan until Friday. Try to keep positive - the MW could be completely wrong remember..
Stacks, brilliant news about your dates! They may seem like ages away but they'll creep up :)
Fluffy, I had lots of mega weepy moments in the second trimester - seem to have calmed down a bit now though! Managed to keep most away from DH though, so I didn't make him soggy on a regular basis!
Ninja, completely with you on the almost permanent heartburn. I'm living on Rennies most days - some days are better than others. Oddly gaviscon wasn't that effective for me...
