Day 4 Update

Time flies πŸ™‚

So, the recap:

  • Day two had ten fertilized eggs.
  • Day three had nine fertilized eggs. Seven of the embryos had eight cells each. The other two had seven cells. All are progressing normally.
  • Day four, today, we still have nine embryos. Eight had just entered the morula (fourth pic down) stage. Today (day 4) and tomorrow the cells in the embryo will continue to divide until there are 30 or so cells in the embryo.
  • Around day 5 some of the cells will move towards one side of their shell, called the zona pellucida, leaving a fluid filled sack, called the blastocele, in the middle of the embryo. The cells will start to clump into two groups. The inner group becomes the fetus and the outer group becomes the placenta. Amazing.

That’s all for the biology lesson for today πŸ™‚

p.s. I forgot to mention that we did not have to do ICSI. Cilla’s eggs were fertilized naturally, if you call being fertilized in a dish naturally πŸ™‚
