I was told at my nhs 20 weeks scan aswell as it being on my file. I had 2 due to position one at 19 and one at 22 weeks that my placenta is high posterior. I had a private scan today im now nearly 30 weeks and she mentioned that my placenta is infront of my womb now im confused does this now mean its anterior??? I didnt think it would change so far speshly from posterior to anterior?
