What happens after embryo transfer on each day?

Supposing that the embryo continued to develop and that pregnancy occurred as expected, this is what one should expect from Day Post Transfer (DPT) 1 to 11 approximately:

  1. The embryo turns from a 6-8 cell embryo to a morula
  2. The cells of the morula continue dividing: the embryo reaches the blastocyst stage
  3. Once a blastocyst, the embryo starts to hatch out of its “shell”
  4. It begins to attach itself to the uterus
  5. The implantation process continues: the embryo attaches deeper into the uterus
  6. The implantation process continues
  7. The embryo implantation process finishes and the cells that will form both the placenta and the fetus begin to develop
  8. The production of hCG starts, and it begins to enter the bloodstream
  9. Fetal development begins and hCG levels continue doubling
  10. Fetal development continues and hCG levels continue increasing
  11. hCG levels start now to be high enough to be detectable by pregnancy tests
