20 week scan

Shaylee

I got my 20 week scan and was told i have vasa previa.. an extremely rare and dangerous condition in the placenta and umbilical cord. and then i went and saw a high risk dr and they said i do not have it and i actually have a 2 placentas technically. one in front and one in back... i’m just confused on how i have two.. has anyone else ever had this situation
