no morning sickness today

Carli
Hi everyone! 
I'm currently 6 and a half weeks pregnant. The past 4 days I have had morning sickness (1 day I threw up and the rest I was just very nauseous and dry heaving) but today I have no nausea or throwing up. I've had 2 miscarriages prior and am worried to death that my symptoms are going away impending a miscarriage. Has anyone had morning sickness/nausea that came and went and wasn't an every day thing?
