Worried Mama

Rebecca
I need your ladies help! Today I had my anatomy scan with the MFM (high risk specialist doctor) at 22 weeks. I never thought they would tell me anything other than the fact that they were both healthy babies. Instead the doctor only gave me two results, one baby A the girl had a bright spot on her heart. With no other markers for Down syndrome but told me I was to far for the blood testing they would normally do. And the second result being that baby B the boy, was measuring in the 6th percentile for babies his age, and only 14 oz vs his sister who's in the 40th percentile at 1 pound 1 oz. has any other moms gotten results similair? I'm more so worried about the boy being so small because I know the bright spots can be pretty common.
