I am 11 + 5 days. From 4 weeks to 9 weeks I had terrible nausea. Now that has gone away, and I don't feel sick, but have this constant feeling that I am about to gag at the back of my throat. About once a day it actually makes me retch and throw up, and I can't stop retching till I have emptied my stomach, but I don't actually feel sick! It is SO weird. Has anyone else had this symptom? did it go away?
