Morning (all day) sickness

Anna • Emergency RN, wife of an archaeologist, mom to a 21 year old son and 7 year old daughter.
I am only 5 weeks and am pretty queasy and this may seem weird but I also seem to have a metallic taste in my mouth all the time which makes the nausea worse. Does anyone have any ideas on safe ways to combat the nausea? Ginger doesn't seem to be working. ... help!!
