Describing the transition from late pregnancy into early labour - A prospective cohort study.

OBJECTIVE

The time between self-assessed first symptoms and clinical confirmation of labour onset is marked by uncertainty, particularly for primiparas. Accordingly, primiparas often seek professional care to confirm their perceptions of labour onset. This paper describes the transition into early labour among primiparas considering their level of certainty in labour onset and their perception of labour onset symptoms prior to birth.

METHODS

A prospective exploratory cohort study was conducted in Germany between July 2020 - March 2021 among a convenience sample of 69 primiparas. Respondents recorded in a non-validated questionnaire their perceptions of nine symptoms and degree of certainty about labour onset every day from 37 weeks gestation. Descriptive analysis included certainty in labour onset and dedicated symptoms in relation to days before birth.

RESULTS

The participants (n=69) reported a little certainty of labour onset up to 32 days before birth and most of them became certain up to four days before birth. Associated symptoms were regular and irregular pain, symptoms of vaginal loss and emotional symptoms. Gastrointestinal symptoms and nausea were not indicated by a majority. Uncertainty of labour onset, however, was indicated up until the day of birth.

CONCLUSION

Although interpretation is based on a small sample size, primiparas are able to self-diagnose labour onset and report connected symptoms up to four days before birth. We suggest calling this time between self-diagnosis of labour onset and confirmed labour onset based on clinical parameters the transition into early labour.
