If you guys haven't already seen it, go watch our first video, which is the development up until week one. Right, so we talked about fertilization, we talked about cleavage, and we talked about the formation of the blastocyst. Right, and then how we got to the end of that, we're going to now go into the development throughout the embryo up until week - and we're gonna mainly talk about in this video gastrulation. We'll have a tiny little peek into implantation, but I don't want to get into too much detail on that. Reason wise, we'll go more into that when we talk about the development of the placenta.
