I am 33 and a mom of two. I had both children with amalgams in my mouth as I did not know any better. I would not get sterilized! Things can change tremendously in life. Not to mention sterilization sets you up for a host of other health issues. See Biker chics website on that issue.

Once you are detoxed from metals, your anxiety may go away or be very mild. I can tell you that even though I had fillings while pregnant and am probably pretty toxic, somehow my children came out wonderful. So don't feel that you can never have any, should you choose too.

Meantime, use precautions not to get pregnant until you should decide otherwise. You can probably be testing for metal levels when you get to that point and see if they are low enough and you feel well enough. As far as vaccines...
Just claim a religious exemption for you children and will not be vaccinated. Give them bottled water etc. It can be done in this crazy world! Keep your chin up!
