Has anyone else been told they're carrying a worrying small baby? I'm 31+1 and have been told she is very small. She is measuring the same as a 27 week baby. The midwife said if I wasn't already booked in for a scan at 32 weeks then she would book me in for one to check everything's ok. Is this common? I already have a low-lying placenta, could this have anything to do with it? Many thanks in advance.
