when i went for a scan at 5 weeks they couldnt see anything but the sac. i was terrified something was wrong but it was just too early to see anything. most of the websites i looked at said that you wouldnt expect to see an embryo until the end of week 5, sometimes even later. i hope this is just the case for you and it was too early to see anything. i actually posted a thread on this website after my scan asking if anyone else had experienced the same thing and lots of girls posted and said the same thing had happened to them at early scans and they all went on to have healthy pregnancies.

anyway, best wishes. i hope it is all A OK.
