My strat is to use the balanced meal and getting both craving items I've beaten day ten multiple times but when it gets to the overdue level I never have enough points. I've gotten 22,000 nutrition points before that level utilizing multiple skills to gain points. Maybe my luck is just ass but man it's maddening that I can't beat overdue on either pregnancy mode. Still having fun but man this is getting annoying at how I can't beat this level.
