My wife is pregnant. She does nothing, just lays in bed on her phone all day. I have a plan for how to move forward, as I've personally been slacking recently, and could do a better job of leading our family. However, what should I reasonably expect? We've already had one miscarriage and I don't want to push her at risk to my child. I know she's supposed to be tired and sick, but how can I gauge whether I'm expecting too much from her, or not expecting enough?

I've read through a few of the pregnancy-related posts here but nothing really answered my question.
