I guess we will sit tight and wait till next week. I hate the waiting!
We did the dangerous thing and started dreaming about life with a little critter in our life too, and this has sort of shaken that. It's hard not too when it is all you want!
But yes there are no other 'negative' signs, just the perhaps-too-early ultrasound. It was an internal ultrasound too (sorry I forgot to answer someone earlier).
