Thanks for writing to HCM
Your report suggest that total placenta previa
Earlier scan report depicts that placenta was totally overlying internal os whereas in present scan it shows that only 4.94 cm of placenta is overlying internal os (placenta is posterior with grade II maturity)and improvement is due to migration of placenta with advancement of pregnancy
.There are chances that it can migrate more,so that repeated scan is necessary in your case.
Other findings include you have single foetus,breech presentation
and adequate liqour.
Wish you all the best.
