i had my anatomy scan yesterday at 21w1d. they said baby was very active and healthy, but she was measuring a little small. she was about 20w4d. has anyone else been told this? should i worry? they said it could be because i’m so tiny (5’2 105 lbs before pregnancy) and that i will probably have a small baby. kinda worried, but they did say everything was healthy so idk. thanks for the help!
