What is "basal body temperature"?

Basal body temperature is different for everybody. Most women hover in the 98 to 99 degree temperature but if you were to check it every morning, the LH surge is associated with a slight rise in body temperature. By slight, I mean a half a degree. So if you are running 98.4, 98.3, 98.4 in basal body temperature consistently every morning and then you wake up and your temperature is 99, that does suggest ovulation.
