A few days not just overnight.
Its ok. I've had a baby so I know.
some of these doctors will tell the women to go home and come back later when the pains are closer together, then they camp out in the parking lot because they don't want to risk it and within an hour or so some of them are admitted.
They won't send you home until the child is delivered, and there are no post-natal problems. Night and day are irrelevant.
