Pro safety adviocates found some toxicity, and the base chemicals have high percentage rates of problems which can harm fetus. The below link will take you to the mnost reputable information about the product.
I hope this information on the consumer information website helps you make an informed decision. On your next visit to the doctor, perhaps you should print that information out so he can made a judgment call with you as to the risk. However, with the amniocentis, and regular blood work and great ob care, if there was anything suspicious your doctor can follow up with treatments.
The EPA and other consmer groups will have more information on the chemicals involved in the product too.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
