"AF" ?: Implantation occurs about 5-7 days after fertilization, and may in fact produce spotting. If not pregnant, a period should start 7-8 days after that. Unsure what is meant by "AF", but if your "period" was light, get a serum pregnancy test (HCG) from your healthcare provider, which is very accurate.
