Will a gluten free diet, while pregnant, cause the baby to be born with a gluten allergy?

I just found out I'm pregnant. I have been on a gluten free diet for approximately 4 months. I was not diagnosed as having an allergy, however, when I go without eating gluten for a long period and then eat gluten, I get severely congested for up to a week. I'd like to continue the gluten free diet, but am afraid that by eating no gluten will cause the child to be born with a gluten allergy. Should I eat little bits of gluten food, here and there, just so that the child has been exposed to it. Or, could that actually cause harm if I do have a true allergy?
