Does anyone know if it is safe to go through metal dectectors while in the first trimester? I know it is a silly question but I was just reading that you should not use electric blankets while pregnant. I thought this was b/c of the heat issue but it turns out it is really b/c they produce a low level electromagnetic field. I am not sure how the metal dectors work but I am assuming they might use an electromagetic field as well. I am thinking about flying during the first trimester and I have jury duty which requires walking through one. I could postpone the jury duty and avoid the trip but wanted to know if I am just being crazy.
