I have my blood test tomorrow and I'm excited/nervous. I'm wondering when I can make the first appt...I'm very impatient!
To keep you all informed, I'm 4 weeks 5 days along but I am in my 5th week. So when I post the size and information for Little Kob's development, it might be a little confusing since different websites say different things.
fitpregnancy.com: Your embryo is about two millimeters long, about the size of a grain of sand. Your baby transforms into a bundle of cells organized in a C-shape with a top, bottom, front, and back. A groove has developed on the embryo's back, which will seal and develop into the neural tube (which later will become the spinal cord). At this point, the tube already has a wider, flatter top that will grow into your baby's brain. A bulge has developed in the center of the embryo, which will soon become a tiny U-Shaped tube which will form the heart. Your embryo is encased in protective membranes and attached to a yolk sac, which manufactures the embryo's unique blood cells.
