I feel for you Cheryl. I wanted to say congrats on your pregnancy too! I think you had your m/c just about the time my second bean got stuck! Luckily my wait was only till I knew bean was stuck in good too. i.e 6 weeks! I didn't really feel confident that everything would be fine until after the 12wk scan though.
I think 2nd beans are much more sticky - just take each day by day and I'm sure everything will be fine!
Oh yeah and I think you never stop checking for blood when you go to the loo - it must be something that sticks around for the whole pregnancy!
