Generally: The temperature rise occurs after ovulation, usually about 2 weeks before the period starts. 4. About a week or so before my period starts, during my period and sometimes a few days after ,I run a temperature that ranges 99 - 100.
Before ovulation, during your follicular phase, basal temperatures are relatively low. After ovulation, your basal body temperature rises sufficiently that you can see the difference between your pre-ovulation and post-ovulation temperatures when they are plotted on a graph.rogesterone, however, also causes the resting body temperature to rise after ovulation. Because progesterone is only secreted in high levels after ovulation, it is possible to identify ovulation for the day BEFORE the temperature rises when temperatures are plotted on a graph.
