The process and result of pregnancy are the main wellness factors not only internal, but also the whole hu-man-s life. Such pregnant complicates as gestosies, placental disorders, fetal-s internal hypoxia are accom-panied row of metabolically and hemodynamic changes, having common non-specific character. One of the wide-using methods able to estimate the character of such changes is the extended repro-duction variation cardio rhythm method. Last 10-15 years this method was used for the vegetative nerve sys-tem analysis, humoral metabolic and hormone regularity at pregnancy. With the help of main and additional components spectral dynamical cardio-intervals row was studied cardio-rhythm variations at women on the 1st and 3d pregnant terms. Using the additional components in the whole spectral capacity (patent R. Ph. N 2315557 at 07.11.2006) have made it possible to establish the account of different levels vegetative nerve system regulation and endocrine system in women-s different pregnant dates, to compare and find peculiarities. Our results demonstrated that the spectral-power means of pregnant women with the 14 weeks period are the same with the healthy non-pregnant women. The cardio-rhythm autonomic-level regulation is mainly lowed at women in the 3d term. The VLF part component predominates in the common spectral power structure at 3d term pregnant women; this demonstrates the humoral-metabolic and central cardio rhythm prevail process, where oversigmental vegetative nerve system and hypothalamus levels dominate. Variation of cardio rhythm means give the early diagnostic and well-end pregnancy prognosis possibili-ty.
