I'm a diagnosed Coeliac and I too have had incredible cravings for things I can't have - bread, burgers in buns, sandwiches. It's very hard. I've been so tempted to cheat and if it wasn't for the accompanying wheat allergy I have (life threatening - anaphylaxis inducing) I would so have given in!
My doctor would be absolutely furious if he thought I had cheated, as I'm sure yours would, as it's not just the short term effects of gluten you have to consider, but the long term. I would suggest talking to your dietician. I think it would be bad practice to suggest you could reintroduce gluten back into your diet without it having any ill effects. I doubt it would do your baby any harm whatsoever, but you have your own health to consider too.
