May I please ask what plans you have in case of congenital abnormality? Say, for example an abdominal wall defect? They are rare, but I've looked after dozens of babies with one, and it's care of the exposed gut in the immediate post-natal period that make the difference between a baby with a working gut and one without. [wrap gladwrap round their middle and call and ambulance is probably the best thing to do]. A baby with something like a diaphragmatic hernia, 1 in 2,500 births, or PPHN, 1 in 2000 births, simply wouldn't survive, and although 1 in 100 babies are born with a congenital heart defect, not all are picked up antenatally anyhow, but there are a number of congenital issues where being aware of the possibility might make a difference in the unlikely event of giving birth to a baby with a problem.
