Your not the oonly one my baby girl weighed about 11oz at 20 weeks I'm now 24 weeks n doctor will check her again he said her birth weight might only be 5 or 6 pounds. But it's hereditary because I was 4lbs n my family has a history of small babies
According to this week to week app. It baby is bigger then what it says she should be. It says at 18 weeks the baby should be approx 5 ounces and at 20 weeks your baby should be around 9 ounces. I would mention this app to the doctor and ask him why he is thinking your baby is
Small or not growing fast enough.. In 2 weeks the baby has almost gained 3 ounces. That's pretty good . I'm on my 3rd baby. And mine has always matched this chart according to my Dr.
I come from a family of big babies. My son was 8lbs 5oz when he was born. She is not matching the charts... Charts show her being in only the 5th percentile. I go Friday and I'm hoping she is over a pound!
