Craving weird things..31 weeks pregnant.

So with my daughter right around this time I craved sand... yes sand. And comet the cleaning powder.

It was AWFUL. I of course never gave into it.

But now I'm craving the same two things.

And it's sooo bad. It's all I think about when I'm hungry or when I eat.

I know not to think too much into it.

And I definitely know not to eat either one of those things.

Bur I guess good Ole Google said I should consult my doctor as it could be a sign I'm missing something like iron and such.

Anybody else have this problem? And what was your outcome?
