Help! Horseradish is bad if you're pregnant?!?

Amber

I'm 10 weeks pregnant and had horseradish on two sandwiches last week and I was craving horseradish again. I was about to eat another sandwich with it and thought I'd just look it up to be sure. What I found online was so alarming! It said it was imperative to avoid it and could cause miscarriage. Is this true?! Anyone eat it while pregnant?
