The life span of an ovum is considered to be 1-2 days after ovulation. During that period, the sperm encounters ovum by having sex, resulting in a fertilized egg. The fertilized egg moves through the fallopian tube to the uterus, repeating cell division. After the fertilized egg arrive and stay at the endometrium, the implantation is completed about 9 to 10 days after fertilization.

A Small Amount of Bleeding when the Fertilized Egg is Implanted in the Uterus
