I think it could be a combination of maybe the stress and possibly maybe you got a bug. I know when I am really stressed or worried about something I will get so sick and puke and have D really bad. Now I take Xanax when I feel the stress building and it stops all those symptoms in there tracks. If it lasts longer than a week or if you develop more pain and start vomiting again I would definetly call your doctor. (((HUGS))) hope you get feeling better.
