At this early stage of prenatal development, the embryo is called a blastocyst. Implantation of a fertilized ovum is most likely to occur about 9 days after ovulation, but can range between 6 to 12 days.Use this calculator to find the most likely date range for implantation based on your cycle:t this early stage of prenatal development, the embryo is called a blastocyst. Implantation of a fertilized ovum is most likely to occur about 9 days after ovulation, but can range between 6 to 12 days.
Implantation is the process by which a fertilized ovum (egg) implants into the uterine wall to obtain oxygen and nutrients from the mother. This usually occurs between 6 and 8 days after conception. Conception itself can occur anywhere between a few hours and 5 days after intercourse.rom this point on, the embryo must travel down the fallopian tube to implant in the uterus. This can take about a week. Only after implantation can you tell whether or not you are pregnant. This is because after implantation, the part of the embryo that becomes the placenta begins producing a hormone called beta HCG.
