First week
After fertilization of the ovum by the sperm, egg cells begin to divide. This egg then travels along the fallopian tubes to reach three or four days in the uterus where it will bind. The outer part of the egg, which will be later the placenta begins to implant itself in the uterine wall, causing the production of the hormone HCG, which is at this stage not yet detectable by pregnancy tests .

The cells continue to divide to form the tissues and organs. The egg is already becoming an embryo. In the middle of the second week, it is actually implanted in the uterine wall, as the future placenta which already allows to bring blood and oxygen to the so-called “embryonic disk”. It was also at the end of this week that the pregnancy tests can detect the hormone HCG , and therefore you indicate your pregnancy.
