Nausea

Im just over 6 weeks. My stomach has felt uneasy alot and NOTHING aggrees with it. I don't eat in big portions and have to eat very bland things. Instead of throwing up i feel like im in the bathroom a lot during the day. Im thankful im not throwing up, but ugh i just want to eat normal. Im trying to stay healthy but it's almost impossible at this point. Anyone else have this problem?
