What are elevated Basal body temperature?

Answer 1

During your menstrual cycle, an elevated basal body temperature indicates that you have entered your luteal phase. This means that you have ovulated and moved on from the folicular phase. During the first part of your cycle, your body produced estrogen which lowers the basal body temperature. Once ovulation occurs, the body begins to produce progesterone, which causes basal body temperature to rise slowly until your period comes. Throughout your cycle, your temperature should rise and fall, but it is considered an elevation when the temperature rise above a cover line and stays elevated above it.
