Since celiac is a condition of the auto-immune system, it's possible that you
may have other auto-immune problems that can interfere with pregnancy.
 Hashimoto's syndrome (hypo-thyriodism caused by auto-immune factors) can
disrupt hormonal activity and make it hard to get pregant and/or keep a
pregnancy to term.  There are other, more technical auto-immune conditions
related to infertility, but be sure your thyroid is checked first!  Also,
consider seeing a reproductive endocrinologist rather than an OB right away.
