@Shireen32,  Take some deep breaths.  Your labs are fine!  Your tTg IgA is so low!  Well done!  Your endomysial IgA is fine.  There's not a level on the endomysial test.  It's just "yes or no" for if you have celiac disease.   No, it's too early to call it refractory. What are you eating?  Please tell us more than meat and veg. Do you consume dairy? Do you consume processed gluten free foods?   Are you taking any prescription medications, herbal supplements, vitamins and minerals?  

thank you knitty kitty I don't have a vitamin deficiency and I supplement omegas.  Are there other more mild symptoms that co-occur with your joint pain as well @Moodiefoodie? I am suspicious my own joint pain could be related to another autoimmune issue. I am wondering if it is Crohn's or something similar because I've continued to experience some issues despite having normal celiac antibody levels. What have you considered?

Here are some more publications on this topic: https://www.celiac.com/celiac-disease/celiac-disease-amp-related-diseases-and-disorders/fertility-pregnancy-miscarriage-and-celiac-disease/ 

Yes, it could be. Anti histamines help with the symptoms but I don't really like to take them long term.  

There is a product call Quinoa Flakes that might be a good substitute for oats.
