scared mom looking for help!

Ann
Everything has been going great through my entire pregnancy then last week at my 38 week appointment my dr said my stomach was measuring small. I had an unltrasoind and baby is measuring 6pounds but a couple weeks behind on most measurments.. my Dr said not to worry but they'll just monitor me closely.. then at my Non stress test I noticed "IUGR" on my chart.. googled it and am in a state of shock.. any moms out there able to give me any advice? I'm 39 weeks going back for another ultrasound today and just so scared.
