So over it, and i've hardly begun

Alexlouise

 So on the 1st day of my 12th week my nausea and vomiting was gone. I felt pretty good. Then this last thursday I had pancakes and have since been miserable. My nausea and vomiting has returned full force becoming all day nausea. I dont get it. I thought the worst was over. Anyone else experience this?? Then on top of that i've been getting this stomach ache. Feels like gas is trapped. Its so painful and my tums dont seem to help much... Hope i feel better soon. Tomorrow starts week 14
