Sometimes the reason for the baby not growing is because there is too many genetic problems wrong with the baby therefore our body realizes this & the baby stops. Your not alone in this. It happens to many women.
This happened to me alittle over a year ago. If the ovum doesn't miscarry itself you will most likely have to get a d&c. I'm so sorry for your loss.the doctors could be off on dates but if that's what they are saying than more than likely that's what it is.
This happened to me my first 3 pregnancies
