my DD is 3 weeks old and has spent most of today trying really hard to poop and has been unsuccessful as of yet

every time she falls asleep she wakes up grunting..I called the dr to ask if there was anything to do to help but they said not unless her stomach is hard..I've done bicycles with her legs and that seems to relieve her for a little while but I just feel really bad for her and helpless at this point..anyone have any tricks?
