they probably couldn't get a good view of
it. If it's too low, they can't get the
wand in a position to correctly measure
everything. It's nothing to worry about.
Like bridget said, if it's the placenta,
it's a little more to worry about. Because
if it's covering your cervix, you will
HAVE TO have a c-section, or else there's
a HIGH chance you'll bleed to death
Good Luck!
