Nausea and constipation

I'm 5w4d along and today the nausea just hit me and it was horrible to say the least. On top of that, I'm majorly constipated which is so painful. God bless my mother and husband though because they are going out of their way to make sure I'm comfortable and have what I need. My mother just went out and got me some Citrucel and Metamucil (mind you its 10:30pm) and my husband is brining some stool softeners and prune juice and fruit for me on his way home from work now.... I cannot imagine feeling this for any longer than necessary. Who is is going through this? What are you taking for the nausea because I'm not sure what's safe to take for that, unfortunately.
