Implantation of a fertilized ovum is most likely to occur about 9 days after ovulation, but can range between 6 to 12 days.
If the sperm is too early or late, it cannot form an embryo. Ovulation, which is the release of eggs, typically happens around 12 to 14 days after the first day of a period (or the start of a new cycle). Implantation occurs 6 to 12 days post ovulation.
