@Divya, Ordinarily Sadhe Sati come three times in the life of any individual. First in the Childhood, 2nd in youth stage and 3rd in the old age.
First Sadhe Sati effects education and parents, 2nd effects working life and economic conditions whereas 3rd one effects the health of the individual. There are three stage in a sadhe sati divided into 3 periods of two and half years. Correct predictions and solutions can be suggested based upon your Janam Kundli for which exact date, time and place of birth is required. Ordinarily there is no harm in continuing with bearing divya shani naal kavach for sade sati dosh.
