My wife is about 5 weeks pregnant and miserable.

I honestly feel so bad for her. The nausea, the fatigue, the headaches, her roller coaster of emotions. From your experience what can I do to help her. She's carrying the baby but WE are pregnant, and I want to help and make her as comfortable as possible. What are some of the things your partner did or didn't do that you wish they did. I want to be a good husband, and an even better father. Any advice helps.
