IVF Embryo Development

Below is a list of day-by-day developing steps of embryos for IVF or FET.  We will have a better idea how embryos grow inside our uterus, and hence when we can do HPT.

For 3-Day Embryo Transfer:
1dpt … embryo is growing and developing
2dpt … Embryo is now a blastocyst
3dp … Blastocyst hatches out of shell on this day
4dpt … Blastocyst attaches to a site on the uterine lining
5dpt … Implantation begins,as the blastocyst begins to bury in the lining
6dpt … Implantation process continues and morula buries deeper in the lining
7dpt … Morula is completely inmplanted in the lining and has placenta cells & fetal cells
8dpt … Placenta cells begin to secret HCG in the blood
9dpt … More HCG is produced as fetus develops
10dpt … More HCG is produced as fetus develops
11dpt … HCG levels are now high enough to be immediately detected on HPT

For 5-Day Embryo Transfer:
-1dpt … embryo is growing and developing
0dpt … Embryo is now a blastocyst
1dpt … Blastocyst hatches out of shell on this day
2dpt … Blastocyst attaches to a site on the uterine lining
3dpt … Implantation begins,as the blastocyst begins to bury in the lining
4dpt … Implantation process continues and morula buries deeper in the lining
5dpt … Morula is completely inmplanted in the lining and has placenta cells & fetal cells
6dpt … Placenta cells begin to secret HCG in the blood
7dpt … More HCG is produced as fetus develops
8dpt … More HCG is produced as fetus develops
9dpt … HCG levels are now high enough to be immediately detected on HPT
