Your chart starts on the first day of your period. This is the first day that you have red flow (not spotting). This is cycle day one. Take your temperature immediately upon waking up and ideally after 3 or more consecutive hours of sleep. Keep your BBT thermometer next to your bed. Moving, drinking water, smoking, etc. will impact your temperature so it is very important to take your temperature before doing anything else. On your Period View App, select the date, enter your temperature and click save. A blue dot will appear on your calendar indicating your temperature was recorded on that particular day.
