Hi, I am in my 12th week of pregnancy. Until 2 days ago, I was having very heavy vomiting and nausea , vomiting all the time. Since Yesterday, my symptoms have stopped completely and I have not had any vomiting or even nausea. I don t have any cramping or bleeding . My ultrasound is due on 11th. Should I wait for that ultrasound or should I go right away to the doctor. Is there anything to be concerned about?
