I am 30 weeks and was told that I had to see a specialist because my babies arms and legs are measuring smaller than normal. They gave me an ultrasound when I was about 26 weeks and thats when they first noticed it and told me to come back in a few weeks and I came back 3 weeks later and they said my baby was still behind. I am 4ft 11 in and my husband is 5ft 10in and everyone in both our families are all short. Should I be worried about seeing the specialist? My midwife said there is a good chance the baby is just genetically small because I'm small but theres also a chance she has some kind of dwarfism. I'm worried and scared. Please help
