My understanding is that the placenta is too close to the CERVIX. In most cases it will correct itself as it grows and your uterus expands. However if it does not move "upwards" enough it could cause too much bleeding during labour/child birth so it would mean and automatic c-section to avoid this complication.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
