Implantation typically occurs 6 to 10 days after ovulation, or day 20 to 24 of a menstrual cycle. However, it can happen a few days earlier or later. In an average 28-day cycle, ovulation occurs on day 14 with the first day of a woman's period being considered day 1 in a cycle.
Soon after implantation occurs, the embryo begins producing human chorionic gonadotropin (HGC), a key pregnancy hormone. HGC is also the hormone that pregnancy tests detect. Implantation can occur anywhere from six to 12 days after ovulation, with it taking an average of about 10 days. However, it can take a couple of days after implantation for the body to produce sufficient levels of HGC for pregnancy tests to measure.
