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...

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