If "Auntie" is delayed, many women will first check whether they are pregnant by testing the pregnancy test stick.But when they went to the doctor with the pregnancy test stick, the doctor did not look at the result of the pregnancy test stick, but let them go for pregnancy tests, or directly conduct a B -ultrasound.The accuracy of the pregnancy test stick is not 100%.If you test at home, the accuracy of the test results can only reach 50%-90%.Because testing time, environmental factors, and methods of use will affect the test results.
You can test whether you are pregnant in about 14 days after sex.The reason why pregnancy test paper is carried out 14 days after sexual behavior is because it is a hormone secreted by nourishing cells -the value of chorionic gonadotropin (HCG).Only to form gradually, so HCG couldn’t be measured in the first few days of pregnancy, and it was not obvious until about 14 days.It is generally recommended to use morning urine detection in the morning, and the accuracy rate is higher.In theory, two clear red bars appear, which is pregnant.However, the accuracy of the pregnancy test stick is not 100%. If the pregnancy time is too short, it is too early to check that there may be two bars but no pregnancy.
Unhappy: Only one bar appears in 3 minutes.
Preliminary diagnosis of pregnancy: In 1-5 minutes, both bars (control line C and detection line T) are all color, and the detection line (T) color is clear;
Perhaps pregnancy: two bars appear in 1-5 minutes, but the detection line (T) has a lighter color.It is recommended to use morning urine after 3 to 5 days.
Effective or failure: No line appears.It may be caused by the expiration and test methods of the product.
Although the pregnancy test strip was used for testing, the errors caused by the discontinuation time, the concentration of urine, and the accuracy of menstruation, etc. It is best to go to the hospital for examination to ensure that the results are more accurate.
During the first examination, in addition to determining whether the mother is pregnant, the doctor will also confirm whether it is a normal pregnancy. If there are some situations that are not conducive to pregnancy, the doctor can discover and give the corresponding suggestions early in order to take corresponding measures early.
After pregnancy, the secretion of HCG hormone in the body will increase significantly, and it can be judged whether pregnancy can be determined by HCG or urine test HCG.
The difference between HCG and urine test HCG is:
HCG HCG is more accurate than HCG, a urine test HCG
HCG HCG can judge whether to get pregnant earlier than HCG
Urine HCG is a qualitative examination. It can only be judged whether there is a pregnancy. The blood HCG quantitative can find the specific value, which provides the diagnosis basis for unexpected conditions such as ectopic pregnancy, hydatidal tires, and threatened abortion.
However, there is an accident in both HCG examinations: because of up to 25%of fertilized eggs, bed failure will occur, clinically called biochemical pregnancy.Therefore, after HCG detects pregnancy, it also needs to be checked with B -ultrasound to eliminate the situation of biochemical pregnancy.
Generally speaking, it is necessary to do HCG check+B -ultrasound to determine 100%.
Early pregnancy examinations can not only be used to accurately determine whether they are pregnant, but also can diagnose unexpected situations such as ectopic pregnancy, hydatidal, threatened abortion, and abnormal fetal development as soon as possible.But before the inspection, you need to make these preparations:
① If you do urine HCG examination, you must use morning urine urine HCG examination. Note that morning urine must be adopted, because morning urine is concentrated and hormone levels are high.In order to improve the accuracy of the inspection, the amount of drinking water is reduced as much as possible the night before.
② How early the pregnancy examination should be checked? Regardless of whether it is B -ultrasound or other early pregnancy examinations, it is recommended that about 7 days after menstruation delayed. During this period, while confirming whether pregnancy is pregnant, it can screen for ectopic pregnancy and healthy pregnancy.
It is important to discover signs of pregnancy early
Some women have not prepared for babies. Due to various reasons, they are pregnant and may face a choice of miscarriage.If you choose a miscarriage, you can see the pregnancy sac in the uterine under the B -ultrasound. The longer the pregnancy time, the risk of the surgery will increase accordingly.Therefore, it is recommended to decide as soon as possible to decide abortion within 50 days of menopause, and artificial abortion or drug abortion can be selected.
The increase in gestational weeks needs to choose the appropriate abortion method under the guidance of a doctor.For women who want to be a mother, it is even more important to capture early pregnancy information. Once you confirm your pregnancy, you should pay attention to adjusting your lifestyle, avoiding the use of drugs that affect embryos, and avoiding the effects of second -hand smoke and alcohol.
