Hey Amanda. I feel that could be the message for you too...its just such a hard step to take but isn't that always the way to show your faith?!!!!
It will be hard for you to post here and yet 'relax' about ttc, although we don't want to lose you here

You could be like Stef and just concentrate more on the weightloss side and Hiding Place? As long as we know where to find you
And on the otherhand 6mths isn't very long (when I was told in Aug to go away for 6mths I felt like it was forever...but, well, Febs almost here and its flown by!). Are you going to save hard in that time too? So you either have backup for future MA or (and this is the better option) a nice baby-fund for that bfp!
All the best and LOADs of babydust!
