Some have reported having implantation bleeding as early as 6 days after conception. Spotting that occurs about a week after ovulation is likely implantation bleeding, which is typically very light pink or brown vaginal discharge and only lasts a day or two. Bleeding after a vaginal sex is obviously never normal.
Correspondingly, how soon can you implant after ovulation?
Most of the time, implantation occurs about nine days after ovulation, but it can occur as early as seven days or as late as 12 days after ovulation. Once implantation is complete, the cervix becomes closed with a mucus plug.
