*5dt = 5 day transfer, 放5日胎
*Xdpt = day past transfer, 放胎後第X日
this is what happens in a 5dt :
-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
