After 40 days of pregnancy, the pulse is mainly slippery, characterized by three fingers feeling the pulse beating like beads rolling on the line, slippery to and fro, beating a little faster than usual, beating an average of about ten times more per minute. The pulse can be taken at the same time, or separately.
