Ok, I'm probably going to sound stupid, but I'm risking it, lol. When they do the transfer, the embryos need to implant pretty quick, don't they? Or can they just "float" around in there for a while until they attach? Once they attach, they make hcg. Do they implant quick? I would guess they have a certain amount of time to do it? Like I said, I probably sound stupid.
I found this on another thread and I like that it gives a good idea of what is happening during the dreaded tww. And your question isn't stupid! The embie does sort of hang out right and continue growing after the transfer.
This is what happens in a 3dt :
1dpt ..Embryo is growing and developing
2dpt...Embryo is now a blastocyst
3dpt...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 implanted 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
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
