i measured all over the place with DD,mainly way too small they basically said they didnt think she make it she would be less than 4 pounds full term and her stomach was way too small bla bla so they brought her on just over a week early worried she wasnt getting nourished properly and she was 5 pound 5 and perfect so if she went to full term or over she could of been 6 pound or even 7!!anyway im getting the same thing this time and im so annoyed at myself for having an early scan as theyve said "possible down syndrome"because i thought i was 6 weeks 4 days and they saying i was 5 weeks 4 days how can they know soemthing so early??and why stress me when i have to wait so long for the nt scan anyway??sorry that turned into a bit of a vent but im wondering the same,a few people i know were brought on early as told they were having a really big baby but were only 7 pounders???
