could i be pregnant?

I don't know about certain liquids such as milk and smoothies; however, I will try them. If those do not work then I will just convert to water. I know that no matter how many times I've swallowed today after eating the food listed, it always feels like it's coming up. It is making my stomach hurt really bad.

Water is not going to do the job. You need an electrolyte replacement drink, such as Smart Water, Vitamin Water, etc. - available in grocery stores. And you need to read the label to ensure that you are getting electrolytes. Sports drinks such as gatorade or powerade also contain electrolytes, but they have a despicable taste, in my opinion. Vitamin Water is available in a range of flavors, such of them quite nice, and Smart Water tastes just like plain water.

This happened to me before. It will make your period irregular because of all the extra stress.

I just saw that you took the pregnancy test.

Stress will make it hard to eat, too. It can also upset your stomach.
