Seriously Stressed!

 Yesterday I got a message on my machine saying that they needed to repeat the anatomical US on Tabitha and they needed it done before my next dr's appointment.  I just had it done a week ago!  I called and they scheduled me for Feb 4th at 1:45 but told me I'd have to call the dr's office to find out why it was requested.  So I called yesterday about 3:45 and left a message.  They didn't call back and now because of ice hitting the area, their office isn't open today!  I am going crazy with worry and what if and can't possibly find out what is going on until at least Friday!
