Nausea and gagging

I am a 17 year old female and lately I have been feeling sick to my stomach and with that comes the gagging. The first time i noticed it, i just had a sore stomach and assumed that i was either not hungry or that i was hungry but i couldn't decide which, so i just tried to ignore it. Then a few days ago it came back, but what started out as a sore stomach turned into constant gagging until i eventually threw up. Earlier that night i had had my supper and later on had some mcdonalds so i wondered if that was the problem. After that little ordeal i decided to eat something and it seemed to help so i continued on with my night. But since then, off and on i have had the same feelings of an upset stomach and almost threw up once again. This time however, i had nothing to eat that day and had only been up for an hour or so. I'm not sure if its something that im eating, or not eating, or even just going through because of my limited eating over the summer.
I am really confused and I do not want to continue to have these problems, so if anyone has any ideas on what it could be, i'd be really appreciative :)

Welcome to the gastroenterology community!  It is possible you could be pregnant?  Have you been to a doctor about this?

Nope, still a virgin. I have not been to a doctor about it yet because I'm not sure how serious it is.

I would recommend you see a doctor about this to make sure it is not something serious.
