Daily Play by Play

I thought this was very interesting-- I picked it up from Wendy's blog.

Here is what is happening daily with a 3 day transfer:

• 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

Notes: dpt= days past transfer

Blastocyst=an embryo which has developed to the point of having 2 different cell components and a fluid cavity
