Human blastocysts should hatch from the shell and begin to implant 1-2 days after day 5 IVF blastocyst transfer. In a natural situation (not IVF), the blastocyst should hatch and implant at the same time - about 6 to 10 days after ovulation.
When the fertilized egg attaches itself to the uterine wall and begins to produce hCG it is called implantation. This typically occurs between 6 and 8 days after ovulation. The egg is fertilized in the outer part of the fallopian tube, generally within 12 hours of ovulation.After it is fertilized, the egg travels down the fallopian tube. The fertilized egg grows as it travels.
