Do I need to take my temperature while I have my period?
This will very much depend on your cycle length. If your cycles are on the short side and you typically ovulate before Day 11, it is advisable to take your temperature during your period. This will allow enough temperature data to be recorded in order to establish your phase of lower temperatures before ovulation. If you typically ovulate on Day 11 or later, you can skip temperature recording during the first 5 days of your cycle, if you wish.
While you are learning to chart your fertility and becoming familiar with your unique fertility pattern, we strongly advise that you chart your entire cycle.
