Know early pregnancy by taking temperature measurements

If in the period without menstruation, the body temperature increased by 0.3-0.5 degrees C lasting more than 16 days (from the date of ovulation), it can be considered as the earliest signal to conceive.

Menstrual periods, nausea, changes in eating; touching the nipple, pain, nipples and nipples narrower, increased frequency of urination . are early signs of pregnancy, but not sure. Sometimes these symptoms appear late, and menstruation is often early or late.

The original temperature measured when getting up after a relatively long sleep (at least 6 hours), has not done any activity (including getting up from bed, talking, urinating, and heat next to bring the mercury column down).

The original temperature of adult women varies with the ovarian cycle. Every month, there is usually a mature ovule, hatching eggs. The outer shell turns into a corpus luteum, securing a fetal hormone (progesteron). This substance affects the body heat control center and the heat dissipation process of the hypothalamus, making the original temperature of 0.3-0.5 degrees Celsius increase.

To recognize early ovulation and pregnancy, women with normal ovarian function need to measure the original temperature daily. The connecting line of the original temperature will have a double phase shape, ie before ovulation is low, after ovulation increases and keeps above the average.

If the ovulation is not conceived, after 9-10 days, the corpus luteum starts to shrink, the amount of estrogen and progesterone decreases. The lifespan of the corpus luteum is generally 12-16 days, an average of 14 days. Until the function of the corpus luteum is completely degraded, the original temperature will drop at the time before menstruation 1-2 days or on the first day of menstruation.

If the egg is fertilized, it will move from the fallopian tube to the uterus, after 7-8 days it will turn into an " embryo " that plugs into the endometrium, secrete a stimulant that causes the corpus luteum to extend its life. , continue to produce estrogen and progesterone. The body's original temperature will therefore not drop.

Therefore, even if there is no unusual feeling, if the period does not show menstruation, the body's original temperature is 36.8o-37.1 degrees Celsius lasting more than 16 days - ie beyond maturity the longest life of the corpus luteum - it can be considered as the earliest signal to conceive. If the high temperature lasts for more than 3 weeks, even if the urine is not tested, it is confirmed that it has been conceived.
