Should I worry?

Had our anatomy scan Monday, and they said everything looked great, just that the babies umbilical cord was slightly off from the center. The ultrasound tech told me this and she said not to worry and that they would do another ultrasound when I was 32 weeks just to make sure the baby was growing properly. I really wasn't to worried about it till I got a call from the hospital last night at 7:15PM, and she told me pretty much the same thing. Also baby was 11 oz and baby was measuring exactly with my last ultrasound from 11 weeks.

Has anyone else had this and everything was fine?
