Mollygirl,
so great FS is open to suggestion!!
I am definitely wheat intolerant, had the genetic blood test for coeliac disease and do not have the gene. (though my Aunt is coealic, and mum very sensitive, puts her to sleep) There is such a thing as non-coeliac gluten sensitive. Anyway if you go off wheat for 2 weeks and you feel better, that is a good indication according to my Aunt!!! I don't have to worry about a little bit eg in gravy, but if get carried away get a sore tummy and nasty wind after a couple of days. It's a bit inconvenient having restricted diet, but you get used to it and is pretty healthy.

There is also a correllation b/w wheat intolerance and low iron absorbtion. my iron is low borderline and I've been on iron tabs, and will also get results for that tomorrow.

Definitely think that if something affects you overall health, it would affect conception too.
