Implantation typically happens between 6 and 12 days after ovulation, with the most common timing around 6 to 10 days post-ovulation. This means it usually occurs about a week to a week and a half after fertilization of the egg by sperm
. In a typical 28-day menstrual cycle, ovulation occurs around day 14, and implantation usually takes place between days 20 to 24 of the cycle
. The fertilized egg, now called a blastocyst, travels down the fallopian tube and embeds itself into the uterine lining during this period
. The implantation process can take several days as the blastocyst burrows deeper into the uterine wall and begins to establish connections with blood vessels to support pregnancy
. Some people may notice symptoms around the time of implantation, such as light spotting (implantation bleeding), mild cramping, or other early pregnancy signs, but many do not experience noticeable symptoms
. In summary, implantation happens roughly 6 to 12 days after ovulation, most commonly around 8 to 10 days post-ovulation, marking the beginning of pregnancy at the cellular level
