Study Summary
The purpose of this research study is to compare the effectiveness of two natural family planning (NFP) methods that are provided over the internet by the Marquette University Institute for Natural Family Planning. One of the NFP methods is the use of a hand held electronic hormonal fertility monitor. The other method involves the self-observation of cervical mucus to track fertility. Both of the methods will involve placing information about fertility into an online charting system that automatically displays the days of fertility and infertility. The investigators are also interested in the influence of mutual motivation by the woman and her partner in using these methods to avoid pregnancy. The investigators hypothesize that there will be lower unintended pregnancy rates among those couples who use the electronic hormonal fertility monitor and among those couples who have a strong motivation to avoid pregnancy.
Primary Outcome
Survival analysis of based on unintended pregnancies and correct use menstrual cycles (for perfect use analysis) and typical use (based on total number of menstrual cycles) -- to be calculated at 1, 3, 6, and 12 months of use. A Kaplan-Meier survival curve over that time period will be displayed to show change.
Interventions
