1. Do your observations regularly and accurately.

Your ability to identify the times of fertility and infertility is directly dependant on regular and accurate observations. Carelessness about the observational routine interferes with successful use of the method, and lowers your confidence and ability to interpret your chart.

A careful observational routine means checking for mucus 100% of the time before and after urination, before and after bowel movements, before and after bathing, before going to bed, and checking if you get up at night to urinate. A reliable observation is made by using flat layers of tissue, wiping from front to back, deciding on the sensation before looking at the tissue, finger testing the tissue for mucus, and mentally logging it for reference when charting at the end of the day. 100% regular and accurate observations mean greater confidence in achieving your intentions.
