tmi -- bodily fluids , no pic lol

I just found out yesterday I'm pregnant after trying for two years! I had a chemical a year ago so I'm a little on edge this time(okay a lot). Morning sickness has come into full swing this morning, but it was green? Is that normal? I didn't eat yesterday, I know I need to, but my stomach turns when I look or think about food. Is the green vomit alarming?
