Rae, my heroine!

Thanks for the replies, I'll try to stop worrying... it's just that without the scans and the blood test, I'd be sat back in pre-conception saying "It's been 14 weeks! Where's AF?" so I'd like some sort of signal from my body that something's happening. I suppose I have been keeping up with my exercise, at least I've had an excuse to lay off the sit-ups (which I would have been increasing like mad if I didn't know).
