There it is, HCG. This badboy promotes the continued expression of progesterone by the ovaries which in turn activate the growth of a huge number of blood vessels and capillaries in the uterus that nourish the baby throughout pregnancy. Right now, HCG is being emitted by the embryo itself, but after things get further along, the placenta will begin to chuck out HCG. Do not know if the placenta emitts HCG because the placenta is comprised of cells that are presently a part of the embryo , or if non-derivative placental cells just start expressing the protein in response to other signaling pathways. HCG also protects the embryo right now because it is super negatively charged, and will repel Becka's immune system until the embryo becomes larger. In either case, it is there, it activates continued expression of progesterone, and it also protects the embryo.
