High umbilical cord pressure

Vanessa
Hi everyone just wondering if anyone's has experienced this. U/S tech didn't seem to worried but went to check to see if my placenta previa had cleared and it did but them she said that the umbilical measurements where high and she walked out to talk to the ob. Kinda freaked me out. She didn't seem to worried said it was kinda odd baby was measuring just a tad bit below wheight at 2.6 lbs I'm 28 weeks 4 days this was just yesterday Friday afternoon and now the ob wants to see me back Monday! So normally I'm freaked out.
