Welcome to HCM.
You are carrying 9 wk pregnancy
and usg scan reveals amniotic band.
It is quite common and not harmful to you and your baby.If there is no other problem,then it is insignificant. It occurs with previous scar tissue in uterus
like in D & C or other thing.
Need USG scan in later month to detect its presence and baby may appear in breech presentation
or it may cause early labor.
So check up periodically to your gynecologist and take advice.
