Summary

This study looks at different ways to track ovulation and the luteal phase using the Premom app. Thirty women will record cervical mucus, urine test results, and body temperature over three cycles. The goal is to see which combination of signs gives the most accurate picture of when ovulation happens.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help people better understand which fertility signs are most reliable for tracking ovulation and planning pregnancy.
What could go wrong
This is a small observational study with only 30 participants, so results may not apply to everyone. It does not test a treatment or intervention.

Who is studied

This study will include up to 30 adult women aged 16 to 45 years who have natural menstrual cycles and are current users of the Premom smartphone application for fertility tracking. All participants will reside within approximately 50 kilometers of Ottawa, Ontario, Canada. Participants must be off hormonal contraception for at least three months and willing to record daily fertility signs-cervical mucus, urinary LH and PDG test results, and basal body temperature-over three consecutive menstrual cycles. The study population represents healthy women of reproductive age who are already engaged in self-tracking of fertility and menstrual health using mobile technology.
