Why does the body temperature not rise after ovulation?

For normal women of childbearing age, their basal body temperature changes in a certain periodic manner, just like their ovulation cycle. In fact, changes in body temperature are related to ovulation and ovulation. Generally speaking, a woman's basal body temperature is lower before ovulation and gradually rises after ovulation. If your body temperature does not rise after ovulation and continues for a period of time (usually at least two weeks), it most likely indicates pregnancy.

When the corpus luteum is formed after ovulation and the secretion of more progesterone stimulates the temperature regulation center of the hypothalamus, causing the basal body temperature to rise, which continues until the next menstruation before it begins to drop. The basal body temperature in the next cycle repeats the above changes. Record the basal body temperature measured every day on a temperature record sheet and connect them into a curve. You can see that the body temperature is lower in the first half and rises in the second half. This temperature curve with low temperature at the beginning and high temperature at the end is called a biphasic temperature curve, which means that the ovaries have ovulated, and ovulation usually occurs before the body temperature rises or in the process of rising from low to high.

Some people believe that the lowest point before the body temperature rises is the ovulation day, but this does not happen in most cases, and only about 20% of women experience this phenomenon. The fertile period is within 3 days after the basal body temperature rises, and the "safe period after ovulation" is from the 4th day until the next menstruation. Changes in basal body temperature can help women who measure their basal body temperature know if they are pregnant in the early stages. A woman's normal basal body temperature presents a bidirectional curve, that is, it is lower before ovulation and rises after ovulation. If there is no menstruation when the due date comes, the body temperature will not drop after rising and will remain for more than 18 days, which means that the woman is pregnant.

If the body temperature does not rise after ovulation and continues for a period of time, it is best for women to use ovulation test strips to self-test. If the result is strongly positive, then the next two days are the ovulation day, and then measure the body temperature on the ovulation day. The normal result is a drop in body temperature. After ovulation, the body temperature will gradually rise. If this is not the case, you need to use an early pregnancy test to test whether you are pregnant.
