Hi hun, i agree with hannah81 please try not to worry too much yet. Same happened with me. They were worried all the way through as i was measuring small for dates and then i had a period where bump didn't get any bigger for 3weeks. I think they were more concerned as when i was carrying my
DD she always measured big for dates and they were expecting the same this time. Jake was born weighing 7lb 10oz and perfectly healthy. He was slightly smaller than his sister had been at 8lb 8.5oz, but according to my grandad the boys in our family are always born smaller than the girls for some reason? They stay smaller untill around school age and then start to catch up. Jake is still slightly smaller than average (9th centile) but is certainly healthy. I also agree the scans vary wildly. My friend was told she was having another huge baby (had to have c-section with first due to size) and recommended another section at 38weeks, her daughter was born weighing 5lb5oz and was tiny, bless!
