I'm pregnant, can I use the Body Fat Analyser Bathroom Scales with BMI, Muscle and Calories scales?

The body fat scales use bio electrical impedance, sending a safe and very low electrical current through the body. Since the electrical current flows more quickly through water and muscle than bone or fat, the scale measures the speed of the current. Based on that number, the scale estimates body fat using a multi-step, mathematical formula. As pregnant women have water in the womb, the result won’t be accurate.
