I was wondering how long after conception will you notice implantation bleeding?

About five days post ovulation would be just about right for implantation bleeding.

Georgia is correct, around 5 days after ovulation is when implantation bleeding usually occurs, though many women do not have such a bleed at all. Also keep in mind that sperm can survive around 5 days in the female body, so a bleed up to 10 days after sex may be an implantation bleeding.
