How to deal with nausea in pregnancy and trying to keep on top of family life?

I'm about 10 weeks gone and am having a terrible time with nausea! I never actually be sick just feel it all day! My house needs a really good clean but I just cannot get my self motivated to do it because of the way I feel everyday! I also work 16 hours a week which adds to the pressure. Just wondering if anyone has experienced this and how managed everything while feeling like complete crap everyday! Is there anything I can take that's safe for baby? Its really starting to get me down now a's there is just so much to do and I just cannot bring myself to do it! I also have a 5 year old and a 8 year old to contend with! My partner helps a's much a's he can but they just don't get I clean like we do! Please help!
