The expansion grade scale ranges from 1 (least expanded) to 6 (completely hatched).
Grade 1: the fluid-filled cavity takes up less than half the space of the embryo.
Grade 2: the fluid-filled cavity takes up more than half the space of the embryo.
Grade 3: the blastocyst cavity has expanded into the entire volume of the embryo, pressing the trophectoderm cells up tightly against the inside of the zona.
Grade 4: Expanded blastocyst, where the blastocyst has increased beyond the original volume of the embryo and caused the zona pellucida “shell” to become super thin.
Grade 5: Embryo has breached the zona and is hatching out of its shell
Grade 6: Embryo is completely hatched.
So the embryo is given a number grade (1-6), followed by a letter grade for the inner cell mass and then the trophectoderm (A,B or C).
For the inner cell mass:
A: Many cells, tightly packed
B: several cells, loosely packed
C: very few cells
The trophectoderm grading goes like this:
A: many cells, forming a cohesive layer
B: Few cells, forming a loose layer
C: Very few large cells.

What you're seeing here is 1. the early beginnings of a baby and 2. More technically - an expanded blastocyst grade BA. Here's a little bit about that that means!Grade 1: the fluid-filled cavity takes up less than half the space of the embryo.
Grade 2: the fluid-filled cavity takes up more than half the space of the embryo.
Grade 3: the blastocyst cavity has expanded into the entire volume of the embryo, pressing the trophectoderm cells up tightly against the inside of the zona.

Expanded blastocyst - The fluid filled cavity volume is larger than that of the early embryo and the zona pellucida (outer shell) is thinning.
The ICM grading is as follows:
A ----- Tightly packed, many cells;
B ----- Loosely grouped, several cells;
C ----- Very few cells.
The trophectoderm (the inner shell) grading is as follows:
A ------ Many cells forming a tightly knit epithelium (layer of cells that make up the outer surface of your body);
B ------ Few cells;
C ------ Very few cells forming a loose epithelium.
So what? Welllll that means, basically, that it is in good shape, and a better quality than any of the embryos we have ever had!
We also have one to freeze for sure and maybe 3 more!! holy wow! That has never happened!! Frozen embryos means that if this doesn't take, or we want baby #3, then we don't have to do all the shots and procedures right away.
A little about the procedure - warning if you don't like mild gynecological talk don't read this, though it is a blog about making a baby after all!
I had to arrive an hour early to start drinking water and get checked in. You must have a super full bladder in order to do the procedure, it helps push your uterus down so its more accessible. (Here's the warning part) They brought me into the room to get set up, checked my arm band 2374634 times so I actually had my own embryo implanted then they get you in the stirrups. Now remember I have a TAC (transabdominal cerclage) this is tied at the top of my cervix, because of this my cervix doesn't "rise and fall" like most women. It just stays way way up high, which is fine b/c now it holds in a baby so I'll take that "pitfall".
My RE had to use like 4 different kinds speculums (this sounds like a Harry Potter word) and an extra long catheter to finally reach my cervix. OUCH! He then threaded the catheter through my cervix and into my uterus. The nurse yells "patient ready", embryologist yells "embryo ready" we see it on the screen above our heads and then she runs into the room with another catheter. The embryologist's bonnet was fabric with eggs and sperm on it, amazing. We watch the little white blip that is the embryo float into my uterus.
They took everything out and I went to lay back and settle in for my 15 minutes of laying flat when the nurse told me they don't do that anymore! My how things have changed, they also said I have no restrictions and can pick up Colin any time I want. I will have a blood test later to determine if the embryo "took" (if I am pregnant or not).
Then Bill and I went out for a nice lunch together! (Thanks Mom for watching Colin!)
At this point in the process Bill and I have decided that the blog should go dark for a while. Until we are ready to announce a pregnancy or until we begin another IVF cycle (both will take a while) Until then send some prayers our way!!
