I went to the doctor last week for my anatomy scan, they looked at everything and said everything looks good. The only thing of concern was she this was at 20 weeks, my baby should be about 10+ ounces and she said she is only 8 ounces right now and measuring small. Does this mean I might be less than 20 weeks? My due date should be later? Or is my baby just tiny lol. Anyone else been through this?
