Comparative study to determine whether several fertility monitoring products - the DuoFertility monitor, the LadyComp/Babycomp monitor and Clearblue Ovulation tests - are substantially equivalent in performance, and secondarily to determine the appropriateness of labeling information for the DuoFertility monitor.
Condition or disease
The investigators plan to recruit 30 women who are currently trying to conceive, and ask them to use the 3 fertility monitors for duration of 3 menstrual cycles. Additionally, during the study the women will be asked to fill in online questionnaires to assess the usability of the monitors. As the spouse is often a critical partner in the purchase decision and compliance, the investigators will also ask the spouse to complete similar online questionnaires.
