As a teacher, I beg, borrow, and steal worksheets and ideas from all over the place. No one should recreate the wheel, as they say! I'm borrowing this, too, since I clearly didn't discover what happens after a frozen embryo transfer. =)
I've seen this timeline on fertilty forums' message boards in the past, but I was redirected to it recently by Kate and her post, who also borrowed from a friend.
5 day transfer:
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 implanted 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
Hopefully, this is what's going on. My lower back has been hurting all afternoon and evening, and I'm still a bit achey at times, but that's it.
