If an egg is fertilised a woman stops having her period What is meant by the 'period' AND What happens to the fertilised egg HELP PLEASE?
"Period" is a term for menstruation ... the biological cleaning
out of the endometium (inner lining) of the uterus - done to
prepare the uterus to receive the fertilized egg.
The fertilized egg "implants" (sticks to) the wall of the uterus
and develops into a fetus (complete with placenta) which will
eventually be born as a child.
