Baby On Board

So I might be pregnant, and I really don't know how I feel about it yet. I don't want to get my hopes up and than come to find out I'm not pregnant. So it happened on the "1/20/17" so now I'm just playing the waiting game to find out if I really am. I don't know if it's cause I keep thinking about it that my stomach hurts or is it because that's supposed to happen. Any tips or thoughts.
