Implantation bleeding typically occurs between 6 and 12 days after conception, which is about 10 to 14 days after ovulation. It can happen as late as close to the time of the expected menstrual period, sometimes referred to as late implantation bleeding. This bleeding usually lasts from a few hours up to three days and is characterized by light spotting, often pink or brown in color. It is generally much lighter and shorter in duration compared to a regular period.
Late implantation bleeding can occur after 10 days past ovulation (DPO) and is often confused with the start of a menstrual period. Despite happening late, it remains typically short-lived (1-3 days) and light in flow.
In summary, implantation bleeding can occur as late as around 12 to 14 days after conception, close to the expected period date, but it is usually brief and light compared to menstruation.
