Question: can implantation bleeding occur later than 12 days?
Answer: "Implantation occurs 6 to 12 days after conception or day 24 to 26 of your cycle," says Sherry Ross, an OB-GYN at Providence Saint John's Center. Since implantation happens so close to the start of your next period, any spotting you may experience is often mistaken for the beginning of your menstrual cycle.
