How long can pregnancy be measured? Is the result of early pregnancy test paper reliable

4hw.com.cn: pregnancy is a big event for women. Pregnancy is a very big knowledge. Many female friends are very concerned about how long pregnancy can be measured. Let's have a look at the answer.

How many days can I test it out?

Generally speaking, 7-10 days after the same room can be tested by yourself, and pregnancy can be tested by early pregnancy test paper or pregnancy test stick. The longer the time after the room is, the more accurate it is. In short, after sharing a room, the earliest week, the latest about three weeks, can test out whether pregnant.

Generally speaking, in the early stage of pregnancy, women will have a series of early pregnancy reactions such as dizziness, nausea, drowsiness, breast swelling, etc. generally, it will be obvious 10-14 days after pregnancy, and will disappear after three months. Therefore, if the above symptoms of women can use early pregnancy test paper and pregnancy test stick to test pregnancy.

The working principle of pregnancy self-test is to detect HCG value, that is, the value of human chorionic gonadotropin, which is excreted into urine through the blood circulation of pregnant women. The self-test of early pregnancy is a convenient and quick method. The hormone is produced by the placenta and generally appears in the urine after a few days of pregnancy, but due to its small amount, it is difficult to test until 10 to 14 days later. The HCG value can also be measured by blood test in hospital, which is more accurate.

It should be noted that although many early pregnancy test papers show that women can perform pregnancy self-test after missing the normal menstrual period for one day, in fact, not all pregnant women discharge the same amount and speed of hCG hormone, which is different from person to person. If the urine test is done too early, the negative reaction may be wrong.

Early pregnancy test paper and pregnancy test stick can only be used as the first step of pregnancy screening, not as a diagnostic method. In order to avoid ectopic pregnancy and ensure the healthy development of the fetus, we should go to the hospital for further examination.
