I guess I'll just have to wait and see what the bt says...... Although a friend of mine just called after hearing from her sister what's been happenin with me over the last couple of days (I hadn't told many ppl in case something went wrong). She just wanted to let me know that in her first pg she had an ext u/s at 6 weeks that showed absolutely nothing either (no sac, no embryo), she went back a week l8ta and had an internal u/s, and there was a sac complete with embryo inside. Although I don't want to get my hopes up, I'll keep the flame burning a little longer just in case!
