Thanks for the suggestions everyone!

OP- yeah, I didn't cut it out until after my BT. I think I do just have an intolerence, not full coeliacs bc I can eat a small amount like if it was in say tomato sauce or something but not anything major like bread etc. Although it seems to have gotten worse since I've cut it out with just the crumbs on the schnitzel setting it off now. But I've heard that happens bc it's built up in your stomach or something and once you get rid of it you're even more sensitive to it. So yeah I don't think it's coeliacs and I've heard it's hard to diagnose it with the BT so I'm not expecting that to actually come back with anything. But I'm not keen on a gastroscopy anyway. Think I'd just skip that if it's obvious not eating gluten solves the problem anyway iykwim?

I also read that eating gluten if you have an allergy/intolerence or something is thought to be linked with problems with fertility and even miscarriage so I'm a bit scared to eat it at the moment bc of that too!
