I been having light spotting pink for 2 days on an off is that a sign of implementation bleeding?

ImplantationBleeding: Do you mean "implantation bleeding"? Pregnancy test positive? Changes in birth control method? Major change in weight? New medicines started recently? Implantation bleeding is bleeding about 10-14 days after conception — normal and common. It usually occurs about when you would expect to have a period. But, it generally lasts for a short time and is usually much lighter than a normal period.
