No, crack is not fine in moderation, but the chances of getting anything from mercury poisoning to listeria is extremely low in any fish or shellfish, including caviar. The only fish high in mercury are shark, mackeral, and tilefish, none of which I come into contact with too regularly. Also the same deal in unpasteurized cheeses and things of that nature. So enjoy, I would eat a gallon of it if I could afford it, I LOVE caviar!
Re: Eating caviar while pregnant?
I would think so but definitely check with the doc.
ETA: Check the package to see if it has been pasteurized.
I found this, if it seems helpful.

Anything in moderation is fine.
Sorry, but that's not true.
