Hi everyone
Miss B, how are you going? From what I can gather an expanded blastocyst is:
"As the blastocyst continues to accumulate blastocoelic fluid, it expands to form - you guessed it - an expanded blastocyst. The blastocyst stage is also a landmark in that this is the first time that two distinctive tissues are present. A blastocyst is composed of a hollow sphere of trophoblast cells, inside of which is a small cluster of cells called the inner cell mass. Trophoblast goes on to contribute to fetal membrane systems, while the inner cell mass is destined largely to become the embryo and Fetus."
I think it is just before it hatches from the egg and continues to grow. How are you feeling? I can't decide whether my symptoms are in my head or real. Really the main thing at the moment is sore bb, to the point it hurts to roll over in bed! nothing much else. Some vague occasional lower back ache. How bout you?
Hi andie and kerbear!
Jane, i hope you've had some good news this morning!
