when does implantation occur?

[KMamaA]

This is my first ivf cycle, when does implantation occur after a 5day blast transfer? should I feel any pregnancy symptoms or could they just be from the meds?

Hi!

Here is more information than you asked for, but maybe of interest to you!
This is what happens in a "blast" 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


Most of the time any symptoms that are noticed are caused by the medications, until the hcg is high enough to be detectable, at which point, the symptoms may be due to the pregnancy.

Good luck!
