I also was thinking maybe I am worrying about nothing. The issues she is having could simple be asynchronous development.
It is better to err on the side of caution and have it confirmed that you are worried about nothing, than to do nothing and find that she does need help later after she is frustrated!
The good news is that the evaluation is not invasive or painful for the child and it gives you a baseline for when she gets older for noting changes.
It seems that your "mommy gut" is telling you something!
Good Luck!!
