If we take into account the obstetric period, then the first signs in 1 week are absent. The woman's body on the first day just started preparing for ovulation and possible conception. Therefore, of course, the typical symptoms of pregnancy, such as toxicosis, morning sickness, sore breasts and changes in the figure, do not bother the woman at this time. The expectant mother may encounter them starting from about 5 obstetric weeks. But here, too, everything is very individual: in some women, the symptoms of pregnancy are absent for a long time, while in others they appear already on the first day after conception.
