Temporarily off diet

I'm going off the diet for a little while. I think I might be pregnant, and this diet isn't suitable for pregnant or nursing women, as it is very very low carb. I don't feel pregnant, and my husband says I don't look pregnant (he says he can tell), but I am definitely very "late", and I haven't been nursing for at least four months, so it's likely. But usally I "feel" pregnant, so I wonder if this could be a pregnancy that won't continue. This happened once before, and the pregnancy ended after only a few weeks. Well, we'll see. I'll keep you updated.
