The thing with early scans is that its very easy to identify an early one, if she is earlier than she is saying (which i think is likely as why would she waste weeks of ££££) then you can tell easily as those early ones are like fetal pole, gestational sac, embryo measured from head to end of the tail bit. It doesn't look like a baby,maybe a gummy bear. You can get the almost baby look from about 9 or 10 weeks though so is she earlier than that? A dangerous game in early pregnancy but then ££££££. That's what it is all about.
