Feel the mother's womb each time she visits. With the mother lying on her back, begin by finding the top of the uterus with your fingers.
Then see how many months pregnant she is by the number of fingers. Each line is about the width of two fingers.
Normally the womb will be 2 fingers higher each month
At 3 months: the top if the uterus is usually just above the mother's pubic bone
At 5 months: the top of the uterus is usually right at the mother's bellybutton
At 8-9 months: the top of the uterus is almost up to the bottom of the mothers' ribs.
"+" sign: in front of the number if the top of the uterus is above the bellybutton.
"-" sign: in front of the number if the top of the uterus is below the bellybutton.
