It is possible for both men and women to conceive when they have sex without any contraceptive measures. Women who want to know if they are pregnant can do self testing. So, is it accurate to test pregnancy the day before menstruation? What are the methods for testing pregnancy? Let's follow the editor below to learn more!
Is it accurate to test pregnancy the day before menstruation
Generally speaking, the results of pregnancy testing one day before menstruation may not be accurate. Women who delay their menstrual cycle by about 5-10 days will have more accurate test results.
What are the methods for measuring pregnancy
1. The simplest method for pregnancy testing: basal body temperature measurement
Every morning after waking up, bed rest and measure body temperature, which is called basal body temperature. Before ovulation, the body temperature is generally below 36.5 degrees Celsius. After ovulation, progesterone increases and acts on the temperature center, causing the body temperature to rise by 0.3-0.5 degrees Celsius. If the egg fails to fertilize, the progesterone will decrease and the body temperature will return to normal after about a week; If pregnant, progesterone levels remain high and keep body temperature at a high level. The high temperature curve phenomenon in basal body temperature lasting for more than 18 days generally confirms early pregnancy.
2. The most reliable method for pregnancy testing: B-ultrasound examination
Using ultrasound to diagnose early pregnancy is the most accurate and reliable method. On the B-mode ultrasound screen, a circular halo, also known as the gestational ring, can be displayed inside the uterus. The dark area inside the ring is amniotic fluid, and rhythmic fetal heartbeat can also be seen.
3. The most convenient method for pregnancy testing: early pregnancy test strips (pregnancy test sticks)
On the seventh day of pregnancy, a specific hormone, human chorionic gonadotropin (HCG), can be detected in urine, which is beneficial for maintaining pregnancy. In general, when urine is dropped into the detection hole on a test strip, if a colored band appears in the control area of the test strip (some test strips appear red, while others appear blue), it indicates non conception. Conversely, if a clear colored band appears in the detection area, it indicates positivity and pregnancy.
4. The most accurate method for pregnancy testing: blood or urine HCG test
This test can diagnose whether an unexpected pregnancy has occurred as early as possible. Chorionic gonadotropin can be detected in urine around 10 days after conception. You can choose to undergo a urine pregnancy test or blood HCG test in the hospital to determine whether you have an unintended pregnancy.
The above is the content introduced by the editor about whether pregnancy is accurate on the day before menstruation and the methods of pregnancy testing. Through the above content, it can be seen that pregnancy testing is not necessarily accurate at any time you want. If tested early, it is difficult to obtain the most accurate results.
