Just back from my midwife appointment. my fundal height has always been slightly ahead of my dates 1.5 - 2 weeks ahead, which i know is normal. now today im measuring 35cm at 31+4, midwife didnt seem too bothered ans said that she will check it when im back in 3 weeks and send me for a scan if needs be. all my bloods/blood pressure and urine is all great. has this happened to anyone else?
