When a witch is pregnant, it is not good for them to use their Jewels much in the way that they shouldn't during their Moontimes. The reason for this is because the use of the Jewels could lead to a miscarriage in the early months and that is not something that anyone wants to see happen. As the pregnancy progesses, the use of the jewels can cause early labor, which is something else that most do not want to see happen. Because they are not able to access the power of their Jewels, pregnant witches are rarely left alone since the males around her will be attempting to protect her from anything that could possibly happen.
