There are many things that can cause your symptoms. CD is one, but IBS and food intolerances are others.
Please try to not worry too much. In fact I would recommend not being ont this board until you know you need to. A lot of folks here have severe CD and it can be pretty scary thinking that you wil follow their path.
You do not know you have CD and even if you do most do not have severe CD.
