When you are pregnant, it should be the happiest day of your life. In the early stages of pregnancy, if you want to check whether you are pregnant, you usually use pregnancy test paper and pregnancy test sticks. These two tools can quickly determine whether you are pregnant in a short time.

So, can pregnancy be detected 3 days before menstruation?

Can pregnancy be detected 3 days before menstruation?

The probability of detecting it 3 days before menstruation is not high. The shortest time it will take is one month after pregnancy and when the menstrual period is delayed before it can be detected. The latest time it will take is more than 40 days before it can be detected. If the pregnancy test stick shows two lines each time, you are pregnant. The mother may ovulate and implant the embryo early. Some mothers can detect it at this stage, while some mothers may need to use pregnancy test sticks later to detect it. If the mother wants to confirm it as soon as possible, she can go to the hospital for a blood HCG test, which can accurately test whether she is in the early stages of pregnancy. Of course, you should also seek the advice of your doctor.

The test can be done 7-10 days after sexual intercourse, and naturally the longer the time, the more accurate it will be. The principle of early pregnancy test is to test the HCG value, that is, the value of hcg gonadotropin in the body. This type of hormone is produced by the embryo and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is not easy to test it at the beginning, and it will become increasingly obvious from 10 to 14 days.

Pregnancy test methods

1. Measurement of body temperature during ovulation period: Measure your body temperature in bed after waking up every morning. The body temperature at this time is called ovulation temperature. Generally, the human body temperature is below 36.5 degrees before ovulation. After ovulation, estrogen increases, acting on the human body's temperature nerve center, causing the body temperature to rise by 0.3-0.5 degrees. If the egg cannot be fertilized, estrogen levels will decrease after about a week and the body's temperature will return to normal. If you are pregnant, the estrogen level will remain high and will not change, which will also keep the body temperature high. If the high temperature curve of ovulation temperature lasts for more than 18 days, it can generally be confirmed that it is early pregnancy.

2. Early pregnancy test paper: On the seventh day of a woman's pregnancy, a specific growth hormone, human chorionic gonadotropin (commonly known as HCG), can be detected in her urine, which is beneficial to maintaining pregnancy. Under normal circumstances, when urine is placed in the test hole on the test paper, if a printed color band appears in the comparison area of ​​the test paper (some test papers are bright red, and some are dark blue), it indicates that you are not pregnant. On the contrary, if a clear printed color band appears in the test area, it indicates a positive result, indicating pregnancy.

3. B-ultrasound examination: Using B-ultrasound to diagnose early pregnancy is the most appropriate and reliable method. On the B-type ultrasound screen, a circular halo can be displayed in the uterus, also known as the pregnancy ring. The shadow inside the ring is the amniotic fluid of the pregnant woman, in which the regular fetal heartbeat can also be seen.

According to the description in the previous article, everyone should know that testing in the first three days of menstruation is not accurate. If the test is performed 3 days after the menstruation is delayed, the test result may be more accurate.
