If you have adverse reactions to wheat products after provocation (even tiny amounts should trigger the effects), then it's indeed likely that you do have coeliac disease. About 1% of population have it, so it's not that surprising. Just remember that a test would require a proper, long provocation, otherwise you'll just get a negative from the biopsy because there's no intestinal damage anymore.

On the other hand, if a diet helps, and provocations after, say, a month (but without your knowledge) make things go downhill fast, you can be sure enough. Welcome to the wonderful life where you get to check yoghurt for trace amounts of wheat products, and pizza is a holy grail (one of my closest friends is coeliac, for people in Amsterdam area, Woodstone in Haarlem makes good gluten-free pizza).
