The goal of this study was to look at the psychological changes that occurred in pregnant women during the COVID-19 pandemic, using a standard maternity clinic as an example, and to develop ways to handle the mental health issues that were discovered. Considering all of the above, there is an urgent need for a detailed study on mental health of pregnant women during pandemic and the search for the ways to reduce the impact of quarantine measures on the level of anxiety and depression at pregnant women. The current investigation was carried out at Kyiv City Maternity Clinic No 1 consultation and diagnostic department. To complete the study tasks, three stages were selected. The pregnant women who met the inclusion criteria were those who were pregnant at the time of the study, had one healthy foetus, gave informed consent to participate in the study, and did not have any serious psychological illnesses. To investigate mental health, we used the Spielberg-Khanin test. The second stage was engaged into correction of psychological changes at pregnant women, where the developed author’s algorithm was applied.
