I went for my 28 week appointment and got told I am measuring massively small for my dates. So I need to go have another scan to check what the baby is up to. Just wondering whether anyone has had this and whether it's a big deal? I always measured small with my boys and they were normal sized when they came out. This bump is smaller but I'm being told I won't be able to have a home birth now and I don't understand why :/
