On what day do eggs lodge in the womb?

Eggs typically lodge in the womb, or uterus, about 6 to 10 days after ovulation. This process is called implantation, where a fertilized egg attaches itself to the uterine lining. Ovulation generally occurs around the midpoint of a woman's menstrual cycle, so implantation usually happens around days 20 to 24 of a typical 28-day cycle.
