Too high, could be you are farther along than you think, multiple pregnancy, lots of
things. Too low, and you may NOT be as far along as you think, or the pregnancy
may not be proceeding along the normal way.
So....not much insight that I can give you until you get those second results. I hope everything is ok, in the meantime all you can do is keep your good attitude and have faith that all is going well. Take care!
