Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Premom App Users
Women aged 16 to 45 already using the Premom App, who will track daily fertility signs over 3 menstrual cycles.
Premom App-Assisted Fertility Tracking
Participants use the Premom smartphone application (Easy Healthcare Corporation) to log daily fertility indicators - cervical mucus (CM), urinary luteinizing hormone (LH) strips, urinary pregnanediol glucuronide (PDG) strips, and basal body temperature (BBT) - over three menstrual cycles. Both participant-read and AI-interpreted app readings are compared to identify ovulation and luteal phase length. \*\*This is an observational study. Participants are not assigned to any intervention; all fertility signs collected are part of their existing self-tracking using the Premom App. The study analyzes these naturally occurring data to compare marker pairings for identifying ovulation and luteal phase length.\*\*
