Hi Ladies, Im 21 weeks and today went for a massage and they had an electric blanket on the bed (it was on very very low) so not much heat. Anyway after that I read you are not supposed to be on electric blankets because of the electric magnetic field or something. So of course now I'm worried. I have had 3 one hour massages altogether. Just wanted to know if you ladies have ever slept or laid on electric blankets while pregnant and was everything okay with the baby. Thanks, you ladies are the best.
