How pregnancy works

Exercise During PregnancyStudies show that the earlier in pregnancy a woman gets regular exercise, the more comfortable she is likely to feel throughout the nine months. The technology harnessed within the pregnancy test involves a biochemical assay called a "Sandwich ELISA" (ELISA stands for Enzyme-Linked Immunoabsorbant Assay -- more on the "sandwich" part in a bit).
Once pee is applied to the pregnancy test, it travels along the absorbent fibers, reaching defined areas that are coated with molecules, called "capture" antibodies, specifically designed to capture hCG. Biochemically speaking, the home pregnancy test is nothing but a soggy antibody sandwich that smells of urine. One of the first detectable signs of pregnancy is a surge in a hormone called human chorionic gonadotropin or hCG.
On average, implantation usually takes about eight to 10 days for normal, healthy pregnancies [1].


If the urine is obtained from a pregnant woman, the reaction zone antibodies will be bound to hCG molecules found in the pee.
From a family planning standpoint, however, this technology can impact us in ways beyond belief.
If one sperm reaches the egg and penetrates it, fertilization occurs.Some women know immediately that they're pregnant -- call it a new mother's intuition. It is around this point on the baby growing timeline that home pregnancy tests can begin to detect the increased presence of hCG. In the case of a home pregnancy test, the substance is hCG and the liquid part is our urine. Each of these zones is coated with capture antibodies, but differ from each other in how they work.


But, aside from the potential for the "are you pregnant" window to induce one into a hyperventilated state, the process happening within that handheld chemistry lab is actually quite impressive. If you are not pregnant, the reaction zone antibodies will just pass on through without saying hello. The outer group of cells forms the placenta, which will provide nourishment.Three weeks into the pregnancy, the blastocyst implants itself into the mother's uterine wall and releases hCG. Her doctor will begin counting the 40 weeks of pregnancy from the start of her last period, although conception normally occurs about two weeks after that.By the fifth week of the pregnancy, the brain, spinal cord, heart, and other organs begin to form.
