Just a thought...
My wife had a miscarriage years ago. It was not a nice experience for her. She was quite awhile getting over it. Who knows what the cause of it was.
However can you imagine if your wife miscarried after a traumatic experience, such as a pitchpole type of accident where she hit something going in the drink? Maybe she hits a wire or the mast or the hull. Maybe she gets knocked out. Who knows...
Would you want this on your conscience. I have heard stories of women going into labour which was brought on by a traumatic experience.
My vote would be to forgo the short term for the long term. Better to ensure junior has 5 fingers and 5 toes....
