Many expectant mothers don't know when it's appropriate to test whether they are pregnant, so how long they can be pregnant can be measured? Many people may still not know. Today, this article will take you to know how long you can test the results of pregnancy and what are the methods of testing pregnancy.
How long can pregnancy be measured?
Generally, it is more accurate to measure 10-14 days after sex.
Generally, sperm and egg cells combine to form a fertilized egg. The fertilized egg needs to reach the female's uterus for normal development. The time for the fertilized egg to arrive at the uterus is about one week. If measured at this time, it is generally difficult to measure, because the placenta of pregnant women will secrete a kind of human chorionic gonadotropin, which is called hCG in medicine It is difficult to detect the secretion of hCG in the urine after the implantation of the fertilized egg. However, after 10-14 days of pregnancy, the secretion of hCG is relatively stable, which is easy to measure.
What are the methods of pregnancy test?
1、 Methods of self testing pregnancy
1. Basic body temperature measurement
In general, if a woman is pregnant, her basic temperature will be slightly higher than her original temperature. She should stay in bed to measure her body temperature after waking up in the morning every day, and record the temperature data for observation. If the high temperature curve phenomenon in the basic body temperature lasts for more than 18 days, then the possibility of pregnancy is relatively large.
2. Early pregnancy test paper, pregnancy test stick
The test principle of early pregnancy test paper and pregnancy test stick is to use a kind of human chorionic gonadotropin secreted after pregnancy. It is discharged with urine and drops urine into the test hole on the test paper. If there is obvious color band in the detection area, it indicates that it is positive, indicating pregnancy.
2、 Methods of pregnancy examination in hospital
1. B ultrasound examination
B ultrasound is the most reliable way to diagnose the fetal heart beat.
2. Blood HCG test
This method can be the earliest diagnosis of pregnancy, when the fertilized eggs in the uterus after implantation, the placenta began to secrete a hormone, it can be detected by blood at the earliest, generally in about 10 days of pregnancy can be detected, if you want to early determine whether you are accidentally pregnant, this method is the fastest and most accurate.
In order to ensure the health of the fetus and the health of pregnant women, it is better to diagnose pregnancy early. If ectopic pregnancy is found, it can be treated in time, otherwise it will be more dangerous to delay one day.
