Implantation bleeding normally occurs a week to a few days before your period would normally start. Spotting that occurs around a week after ovulation is likely implantation bleeding; whereas, spotting that occurs very close to the time that your period would normally start may not be. A normal menstrual cycle generally starts off light and then gets heavier. Spotting can sometimes be the sign of an early period. If this is the case, the spotting will pick up to heavier bleeding. If you have spotting right around the time your period would normally start, it can be more confusing. You will need to take the wait and see approach or take a pregnancy test to determine pregnancy.
