In early pregnancy ultrasound
scans, the difference of upto 1 weeks is acceptable.
As your scan at 6 weeks 3 days showed heart beat of the baby and the repeat scan at 9 weeks showed the interval growth and heart beat of the baby, so we can be sure that the baby is growing normally.
So,this ultrasound report is normal.
Continue taking the prescribed medications and dont take stress
Hope this information is helpful to you.
