Same here Turbochick, make the most of the lack of cramps while you can!
I got my positive test at 5 weeks and the only pain I had at the time was sore boobs I thought 'nice one, this is easy' then week 7 I was DYING with morning sickness!
I was absolutely shattered tired too, that went on about 2/3 weeks then settled down.
I have 4 friends pregnant at the same time as me or 5 if you include me, 2 of us had morning sickness the other 3 didn't have a bit. It seems to vary so much for different women.
Definitely have a chat with the doc if you have concerns, nothing worse than stressing yourself when you're pregnant.
Lucy2010 you poor thing one thing I can't hack is lack of sleep, I hope you get a good nights sleep tonight.
I was up til 2am this morning (stupid bloody nesting, got it into my head I had to iron all of baby's clothes before she arrived

) and I'm so contrary today as a result!
