Occurrence of pregnancy puts a woman in a completely new situation not only physically, but also psychologically and socially. The process of adaptation to pregnancy is individual, depending on a number of factors such as age, current life plans, family and professional situation, or the ability to adapt emotionally. The aim of the study was to assess the degree of adaptation of pregnant women while determining the factors that can affect this process. The analysis considered education, professional activity, standard of living, housing conditions, number of past pregnancies, assessment of marriage/relationship, and parameters of sexual life included in the McCoy Female Sexuality Questionnaire (MFSQ). In the studied group of respondents, factors facilitating women’s adaptation to pregnancy were professional activity and satisfaction with their partner in terms of sexual relations. This process was negatively affected by having children.
