Stomach pains :(

So for the last couple days i have been having terrible stomach pains mainly in the lower part of my abdomen. These pains will get so bad to the point where i have puked each day i have a stomach pain. And i have not bled at all. So i know i am not on my period because i still have more than a week till my next period. Anyone possibly know what could be going on? Id love to try and figure out what this is.
