3 Weeks

Our baby-in-the-making is just a tiny ball consisting of several hundred cells that are multiplying madly. Once the ball of cells (called a blastocyst) takes up residence in my uterus, the part of it that will develop into the placenta starts producing the pregnancy hormone hCG (human chorionic gonadotropin).

Meanwhile, amniotic fluid is beginning to collect around our ball of cells in the cavity that will become the amniotic sac. This fluid will cushion our baby in the weeks and months ahead. Right now, our little blastocyst is receiving oxygen and nutrients through a primitive circulation system made up of microscopic tunnels that connects our developing baby to the blood vessels in my uterine wall. The placenta won't be developed enough to take over this task until the end of next week. (this information taken from babycenter.com)

How amazing! Something so small, is forming right now inside of me. It is such a surreal (and special) feeling knowing that this is going on inside of me! We just found out we were pregnant, which is lucky, because most people don't even know they are pregnant until the end of week 4.

After taking the test, it is very easy to see all the symptoms that I have been experience the last few days: hot flashes (which is strange because I am always cold), dizziness/lightheaded, sleeplessness, tired (going to bed at 9pm), weird cramps/small pains on and off, and a heightened sense of smell.
