Implantation would occur 7 days after conception and since conception takes about 4-5 days you would start implantation bleeding 12-13 days after sex?

I am no expert, but from all that I have read over the past week on this very subject, I believe that it is actually 7 to 12 days after the actual fertilization of the egg (intercourse) that the egg starts implanting and you may or may not have bleeding, or spotting.
