[Cervical status and subjective symptoms in the normal pregnancy].

In 426 unselected pregnant women who came into the routine examination included in the maternity care and who were grouped according to the week of gestation the cervical status was examined and the subjective symptoms were observed. Attention was also paid to the correspondence between the occurrence of the subjective symptoms and the change in the cervical status. In total 984 examinations were carried out. Before the 33rd week of gestation no open internal orifice of the cervix uteri were found. All parities in total the cervix had become shorter (less than or equal to 2 cm) in 7,0 per cent of the cases before the 33rd week of gestation. Subjective symptoms occurred in 19,1 per cent of the cases. Towards the end of the gestational period the changes in the cervical status and the subjective symptoms became more frequent. In all the groups of gestational week the cervical status became pathologic significantly more frequently in pregnancies with subjective symptoms than in pregnancies with no symptoms.
