In the first days of pregnancy, the woman will not notice any symptoms, since it must be taken into account that the weeks of pregnancy are generally counted from the date of the last menstrual period (LMP) and not from the moment of conception.
Once conception has occurred, in the first few days the woman may not notice anything special either, since the embryo is still very small and the hormonal changes typical of pregnancy have not yet occurred.
Therefore, it will not be until approximately the fourth week of pregnancy when the embryo implants in the uterus and the woman may begin to notice certain symptoms. Among them, the most characteristic is the absence of menstruation, but you may also notice changes in the breasts, leucorrhea (increased vaginal discharge), implantation bleeding, tiredness, dizziness and nausea...
