toby maybe the first scan will reassure you? Or maybe as I suspect I will you won't really believe it until you are in labour? 
MissMedusa apparently it's the glycyrrhizin (yes, I copied and pasted that word) which can affect brain development. You would need to eat 100g of pure licquorice a week to have an effect. HTH!
sultanajo that was my earliest symptom - staring into space, forgetting words, being daft, also falling down steps for no reason! I think it's like a pregnancy bubble, and I'm staying in mine! I know what you mean about scans being ages away though. I've just arranged to see my Mum next Tues and my Dad the Monday after to tell them (wanted to do it face to face), so that will help pass the time, having milestones like that to look forward to.
MrsAVB we have to move - our (rental) flat won't have space for a cot, and there's no decent schools for miles. But if you own, I think you can always make the best of your space - we have two tiny bedrooms, neither of which would fit a cot around the landlord's furniture! Plus, once you have bean, you can decide how much you need a garden/garage/ground floor property etc - so hard to know now what's going to be important! Also, re sharp cramps when moving - yes me too. Reassuring, isn't it, when you're not the only one!
Having a very chilled afternoon (at work
) just MN'ing (I loathe my boss and would happily stab him in the eye, this is the next best thing!) and then driving lesson later. I must remember how to reverse around a corner, I must I must I must!
