Due 28th aug 16

I am just over 8 weeks pregnant and had sickness from about 5 1/2 until a few days ago. I had completely no appetite I just drunk juice and ate when I felt I was hungry which then lead me to be sick I would never vomit loads But I was sure to off thrown up once or twice. I seem like I feel okay this is the 2nd day and now am. It worried as I don't feel sick anymore should I be worried does it come and go
