Unexplained Vomiting?

So about two months ago I started having this unexplained vomiting. It happens one or twice a week, I'll just be going along doing whatever (getting ready for work/school, sitting in class ext..) and my stomache just starts to hurt real bad and my mouth gets filled with spit. So I run to the bathroom and obviously vomit. At first I thought it was just the stress from starting college, but I havn't even been stressed lately and It's still happening.
I'm deffinetly not pregnant, I havn't had sex in over a year.
And I'm sure a lot of you are going to tell me to go to the doctor, and I am, but I wanted more opinions first.
Thank you all so much!

I think I eat pretty healthy. Except maybe ice cream every now and then. But normally nothing fatty or greasy or anything.

o gosh.. i honestly have no idea other then really bad stress. just take a break from your studies for a while. education is nothing when it comes to your health

That's crazy!! Is it the type of food that you eat? Do you eat spicy foods or high fatty foods?? It sounds like you might have IBS (Irritable Bowel Syndrome), or possibly a stomach ulcer?? Hmm..it could be so many things. Good luck! I hope you find out what it is!!

We would all just be guessing. It maybe your gallbladder, intestinal virus, ulcer etc.

ok maybe u ate somthing that u ate and it causes your vometing so go to the docter and check what u got

maybe you have some food poison. or like theres something wrong with you stomach. def. get to a doctor soon.
