Can pregnancy be detected at 18 days?

The process of welcoming the arrival of a new life is always full of anticipation and anxiety. Especially for couples who have tried to conceive many times, they will be particularly anxious during the pregnancy preparation period. Therefore, even in the early stages of pregnancy, or when the fertilized egg has just implanted in the uterus, people will seem eager to know whether they are pregnant. Therefore, many couples are concerned about whether it is possible to detect pregnancy at 18 days.

Can I test my pregnancy at 18 days?

Generally speaking, you can do the test yourself 7-10 days after sex. You can use early pregnancy test paper or pregnancy test stick to test pregnancy. The longer the time after sex, the more accurate it will be.

The working principle of early pregnancy test paper self-test is to detect the hCG value, that is, the value of human chorionic gonadotropin, which is excreted into the urine through the blood circulation of pregnant women. Self-testing with early pregnancy test strips is a relatively convenient and quick method of early pregnancy detection. This hormone is produced by the placenta and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is difficult to test it at the beginning and it becomes increasingly obvious after 10 to 14 days. Going to the hospital for a blood test can also measure the hCG value, and it is more accurate.

It should be noted that although many types of early pregnancy test strips indicate that women can do self-tests for pregnancy one day after missing their normal menstrual period, in fact, not all pregnant women release hCG hormones at the same rate and in the same amount. This varies from person to person. If a urine test is done too early, a negative result may be false.

Early pregnancy test strips and pregnancy test sticks can only be used as the first step in pregnancy screening and cannot be used as a diagnostic method. In order to avoid ectopic pregnancy and ensure the healthy development of the fetus, you should go to the hospital for further examination.

What are the symptoms of early pregnancy

In the early stages of pregnancy, pregnant women may experience symptoms such as breast enlargement, frequent urination, mild vaginal bleeding, and may also experience nausea, headache, dizziness, and emotional instability. If you find the above symptoms, you should take an early pregnancy test in time because you are very likely pregnant.

1. Breast enlargement

Your breasts will become extra tender a week or two after conception. This is because in the early stages of pregnancy, due to pregnancy stimulation, the pregnant woman's body will produce a lot of estrogen and progesterone, causing the glands in the breasts to begin to grow. These hormones cause your breasts to retain more fluid, so they may feel heavier and soreer than before.

2. Mild vaginal bleeding

The fertilized egg will implant in the uterus within 6-12 days after conception, which may cause slight vaginal bleeding in pregnant women. If this happens, pregnant women do not need to worry if the vaginal bleeding is mild and there are no serious discomfort symptoms. This is a normal physiological reaction when the fertilized egg implants and is harmless to the human body. Implantation bleeding of the fertilized egg manifests as a small amount of blood or blood spots, which can be seen several times a day. The bleeding lasts for about three days, and there is no discomfort during menstruation. Implantation bleeding of the fertilized egg needs to be distinguished from menstruation to prevent pregnant women from being pregnant without knowing it.

3. Physical fatigue

In the early stages of pregnancy, some pregnant women's bodies secrete a hormone that acts like an anesthetic. Its main ingredient is progesterone, which mainly acts on the uterus. These substances relax the muscle fibers of the uterus, preventing premature pain and allowing the fetus to grow undisturbed. But this progesterone will increase your basal body temperature, so you will lack energy.
