Its normal

Means placenta is  in normal place.Nothing to worry.Its a medical term to exactly pinpoint where the placenta is in the womb

It will not help you to know this term. It has no relevance in the final outcome of the case. Ultrasound scan will be done about 8 times during the duration of pregnancy. And the position of placenta may be seen in different places in all those scans. I think we should be prepared to answer questions like "why this couldn't be seen in the last scan?" and "is there no other way apart from ultrasound to diagnose this problem?"

That's the position of the placenta
