Can pregnancy be detected 8 days after having sex? Regarding this question, relevant personnel said that under normal circumstances, it can be tested through various methods after a week, but everyone's situation is different and errors may occur. What method can obtain reliable and accurate results?

Can I detect pregnancy 8 days after sex?

Generally, pregnancy can be detected 7 days later. Early pregnancy symptoms: amenorrhea: amenorrhea is the most obvious symptom of early pregnancy. If your menstrual period is normal, then if you have amenorrhea and it lasts for more than 10 days, you should think that you are in the early stages of pregnancy.

After menopause, symptoms such as dizziness, fatigue, constant sleepiness, chills, loss of appetite, varying degrees of nausea, picky eating, preference for sour food, or aversion to greasy food and special smells may occur. Some people may experience changes in appetite and hobbies, and more severe ones may also experience nausea. They may also be accompanied by breast pain, darkening and tingling of nipples and areolas, as well as active symptoms such as frequent urination and urgency, which usually indicate pregnancy.

Early pregnancy test refers to urine test, which tests the amount of human chorionic gonadotropin in urine, but it can only be detected when the amount of human chorionic gonadotropin reaches a certain level. Some early pregnancy self-test strips are more sensitive than others. A few days before the next menstrual period, a more sensitive pregnancy test strip may be able to detect a higher concentration of human chorionic gonadotropin.

However, whether you use a regular or more sensitive early pregnancy self-test strip, if the test is done too early, the amount of human chorionic gonadotropin in the urine may not reach a sufficient level to give a positive result. If the test is done after the next menstrual period, that is, about half a month after ovulation, almost all early pregnancy tests will have an accurate result.

Methods of testing pregnancy

For women of childbearing age who have had sexual life and have regular menstruation every month, they can test whether they are pregnant about 40 days after the expected date of delivery. Generally, the first seven days of sexual intercourse, or about fourteen days, or even more than twenty days, are used as the standard for pregnancy testing. In addition, you can use test strips yourself or go to the hospital for examination and diagnosis to test whether you are pregnant. Below is a detailed introduction to several types of pregnancy test methods and their detection time and accuracy:

1. A very simple method to test pregnancy: measuring body temperature during ovulation

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 rises and acts on the human body temperature nerve center, causing the body temperature to rise by 0.3-0.5 degrees. If the egg cannot be fertilized, the estrogen level will decrease after about a week and the body temperature will return to normal. If pregnancy has already occurred, the estrogen level will remain high and the body temperature will also remain 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. The most reliable method for testing pregnancy: B-ultrasound examination

Using B-ultrasound to diagnose early pregnancy is the most appropriate and reliable way. On the B-type ultrasound screen, a circular high score 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.

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

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. In general, when urine is poured into the test hole on the pregnancy test paper, if a line appears in the contrast area of ​​the pregnancy test paper (some pregnancy test papers appear bright red, and some pregnancy test papers appear dark blue), it means no pregnancy. On the contrary, if an obvious line appears in the test area, it means positive, indicating pregnancy.

4. The most accurate method for testing pregnancy: HCG test in blood or urine

This test can initially confirm whether it is an unmarried pregnancy. When the sperm and egg combine and embed into the uterus, the pregnant woman's body produces a new hormone called chorionic gonadotropin, which helps to maintain pregnancy. This type of growth hormone can be detected in urine about 10 days after conception. You can go to the hospital to choose to do a urine pregnancy test or a blood HCG test to determine whether you are pregnant before marriage.
