I have been EBFing and my DD has a dairy allergy. I am suspecting maybe wheat too?

How long does wheat take to get out of your Breast milk and for the baby to feel better, stools and all? I have done tons of research on dairy and it took 20 days for the blood to completely stop and etc, and talking/seeing her pedi. And I cant seem to find anything on the net about a wheat/gluten allergy and breast milk?
