How to detect pregnancy, have you learned it?

There is always such a phenomenon in life that some young female friends have no idea that they are pregnant, which is not conducive to fetal health. Experts suggest that if your period has not come yet, you can determine whether you are pregnant by measuring your basal body temperature, B-ultrasound, early pregnancy test paper (pregnancy test stick), blood or urine HCG test, etc.

1. The simplest way to test pregnancy: basal body temperature measurement

Measure your body temperature in bed every morning after waking up. The temperature at this time is called basal body temperature. Generally, the body temperature is below 36.5 degrees before ovulation. After ovulation, the progesterone level rises and acts on the body temperature center, causing the body temperature to rise by 0.3-0.5 degrees. If the egg cannot be fertilized, progesterone levels will drop after about a week and the body temperature will return to normal; if pregnancy has occurred, progesterone levels will remain high, keeping the body temperature high as well. If the high temperature curve phenomenon in the basal body temperature persists for more than 18 days, early pregnancy can generally be confirmed.

2. The most reliable way to test pregnancy: B-ultrasound examination

Using B-ultrasound to diagnose early pregnancy is the most accurate and reliable method. On the B-type ultrasound screen, a circular halo can be seen in the uterus, also known as the pregnancy ring. The dark area inside the ring is amniotic fluid, and rhythmic fetal heart beats can also be seen in it.

3. The most convenient way to test pregnancy: early pregnancy test paper (pregnancy test stick)

On the seventh day of a woman's pregnancy, a specific hormone, human chorionic gonadotropin (HCG for short), can be detected in her urine. Its function is to help maintain pregnancy. In general, drop urine into the detection hole on the test paper. If a colored band appears in the control area of ​​the test paper (some test papers appear red, some test papers appear blue), it means that there is no pregnancy. On the contrary, if a clear colored band appears in the test area, it means positive, indicating that pregnancy has occurred.

4. The most accurate way to test for pregnancy: blood or urine HCG test

This test can provide the earliest possible diagnosis of an unintended pregnancy. When the fertilized egg is implanted in the uterus, a new hormone called chorionic gonadotropin is produced in the pregnant woman's body, which helps maintain pregnancy. This hormone can be detected in urine about 10 days after conception. You can choose to do a urine pregnancy test or a blood HCG test in the hospital to determine whether it is an unexpected pregnancy.
