Welcome Hotel - congratulations! Could definitely be twins with nausea that early! 
The gas is very deceptive isn't it
- I have it mainly after eating, it was so bad I had to sit with a hot water bottle on my back the other night before I could let out a massive bum rip! OH is the king of farting, I wonder whether his reign will be shorter lived now!
Yeah I'm there with the mild period pains bluesky - sort of feels like a heaviness, but does feel tight, like muscles are stretching. I think it was more the backache that bothered me, but this morning I've woke and it doesn't feel quite as obvious. I don't think wearing my heeled boots helped yesterday!
As for Aspartame, can't really speak for consumption as I've never been a big fizzy drinker - it's always been water, pure orange juice, tea or alcohol for me
- I've not fancied alcohol at all since pg (rare, I'm a lover of white wine) but I'm struggling with the tea/coffee.
How are we all feeling today? DSS is up (OH asleep) and playing Minecraft, waiting Sainsburys order shortly - I bought a CB Digi test and would expect to see 3+ weeks (I last took one a week ago at 2-3) and I think once I've got that I'll give the tests a rest - I dare not even consider how much I've spent on them since start of the year!
