I am 20 weeks and have lost 10pounds my self doctor say not to worry. But its hard
Dramamine (motion sickness meds) were as life saver even the nausea but really bad on vacation
If I was you, I would change doctors. I was having mild nausea not quite puking yet, just the watery mouth and I told my Doctor about it and she said that if I wanted they would prescribe me anti nausea meds.
