Growth scan scheduled

Tara • Maggie`s mommy
I am 37w4d and my dr told me today that I'm measuring small so I'm going in for a growth ultrasound tomorrow afternoon. I'm also not dilated AT ALL but my cervix is soft...so I guess that's good?? Haha I'm a FTM so this is all new to me. 
Can anyone tell me their experiences after a growth ultrasound? Does it mean I'll need to be induced if she indeed is not growing? I'm just a little clueless.
