Thanks for the info everyone. It seems that the whole thing is quite confusing as there are arguments for both sides.

JellyBean, what you said has really hit a cord with me, especially the mercury and autism bit. I work with kids with special needs (including kids with autism) and, while I absolutely love working with them, I can imagine that I would blame myself majorly if I did have it and then my (potential) child had autism. Also, having had a miscarriage last month I am a bit hesitant with taking anything....

I think I might see where I am in my cycle at the time. If I am definately not pregnant at the time I might have it. If I am unsure or definitely pregnant I might hold off until at least the second trimester (and see what my doc thinks).

Thanks again everyone!
