In most cases, you should not discard your basal body temperatures, even if they were taken under less than ideal circumstances and do not look pleasing on your chart. Usually Fertility Friend is able to detect your ovulation and give you a good interpretation even with a few "odd" temperatures. It is best to include them and make a note of the circumstances. When a temperature is not accurate and is preventing you from getting a reasonable analysis, then you can consider discarding the temperatures, though you may want to ask for support before doing so. Never discard temperatures to "shape" your chart to make it look pleasing to you.
