Be sure to keep eating gluten daily until all testing is completed.  Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy: and this recent study recommends 4-6 slices of wheat bread per day:    

You can always to the gluten challenge later, after your pregnancy, should you need a formal diagnosis. I think it's best to play it safe in this case.

Very true. I also suffered from candidiasis which had affected my intestines and toes. I think this might have triggered my gluten intolerance/celiac.

Welcome to the forum community, @Jesmar! The HLA DQ2 and DQ8 genes were the original halotypes identified with the potential to develop celiac disease. Since then, other genes have been discovered that apparently afford a predisposition to celiac disease. As is always the case, these new discoveries are not yet common knowledge and not yet widely dispersed in the medical community. It is not genetically as black and white as we once thought.

It's a moving target, isn't it!
