Am I pregnant?

Paige • 19 y.o. SO Leo 3-29-2015
So about two weeks now I have been getting a belly, I get sick by certain foods, have a lot of mood swings, and  have been going to the bathroom a lot more. I haven't taken a test because I don't want it to be false and then give my hopes up. Should I wait to see if I get my period or just take a test? Please help.
