Kirstiepeck

Hi I'm 21weeks pregnant this is my third baby all my last pregnancies have been fine, but at this ones 20week scan then gave me a piece of paper like they do after and said, there's no consultants here to see you as ur babies head is bigger then it should be and to go home and wait for a call. I got a call a few hours later saying ow it's nothing to worry about it's off the scale but it could be mum or dad have a big head the midwife will be able to keep an eye on the baby. "How with her X-ray vision" I'm just really worried and dontno what to do
