Sometimes it's hard to tell if a client might be pregnant, but if you think a woman may be pregnant, we recommend you use your fingertips for releasing imbalances instead of using a magnet. Simply run the fingertips down the governing meridian, (just as you would use a magnet). This method works just as well as using a magnet, as long as your intentions are clear and strong. It's not that using a magnet on a pregnant woman is necessarily dangerous, but if the baby is born with some kind of defect or problem, you may be blamed! The rule of thumb for working with pregnant women I recommend is:  Be gentle and cautious. Unless their doctor Oks it, don't recommend any supplements, or use the magnets during the course of their pregnancy.
