On day 3 after a 3 day transfer(3dp3dt-3days past 3day transfer) the blastocysts should be hatching out of the outer shell. My shell was thick according to the embryologist so they did what is called assisted hatching where they make a small hole in the outer layer to help with the hatching process. Please pray for our little ones to be able to hatch out of their shells today!!! Go little chickies Go! You can do it!!
Here's a pic of the assisted hatching procedure. The tool on the left is just to hold the embryo. The needle on the right is making a small hole in the outer shell.
