So I had my ultrasound yesterday and my OB's office called this morning to let me know that he had ordered another one that I need to have done in a month...my appt for the 30th of this month also got bumped to mid October...is it normal to have more than one growth scan in your third pregnancy? I'm a little worried, but I'm hoping that if anything was wrong they would have let me know right or told me to come in?
