WE HAVE A HEARTBEAT!!!!!!!!
I burst into tears of relief on the spot. She was pointing out the sac and yolky thing (!) and I was just thinking yeah yeah can we just find a heartbeat first!? And then there it was. Lovely and strong and baby is measuring spot on for dates. My FS was so lovely and saying how difficult we had had it, and how I never complained or whinged (to her anyway :P ) and that she was truly thrilled for us. Its so surreal, but I kept getting teary all the way home - I really am having a baby!!!!
