How many days of pregnancy can be measured. For couples who want a baby, they are very much looking forward to the arrival of the baby, so they will also know about the pregnancy, such as when they can check their pregnancy. The following is about how many days of pregnancy can be measured!
Regarding the number of days of pregnancy, you can measure 1.7 days of pregnancy: the accuracy is small.
Because everyone judges pregnancy according to the concentration of HCG in blood and urine, there is a whole process of HCG concentration change during pregnancy. Even the pregnancy test with water HCG must be carried out on the 9th day after fertilization.
Human chorionic gonadotropin (HCG) water test can only be accurate on the 9th day after fertilization.
10 day pregnancy test: it can be detected according to blood.
Generally speaking, according to the blood test, pregnancy can be detected in ten days. But at this time, the detection of early pregnancy test paper and pregnancy test stick is not very accurate.
20-day pregnancy test: according to pregnancy test paper, pregnancy test stick and urine test.
The basis of 20 days of pregnancy can be measured, but it is still a little early for you to determine according to B-ultrasound at this time. It is invisible to use B-ultrasound for 20 days of pregnancy. At this time, you can try to diagnose the results according to pregnancy test paper, pregnancy test stick, blood test and urine test. If you want to be sure by B-ultrasound, the best time is to wait 45 days.
How many days does menstruation delay count as pregnancy?
The physiological cycle of women is generally 28 ~ 30 days. It is normal to advance or postpone for 7 days, and the cycle length varies from person to person.
But if you haven't menstruated for more than 7 days, it is postponed. The key to delaying menstruation must consider two reasons, the first is pregnancy, and the second is menstrual disorder.
It varies from person to person if you want to diagnose pregnancy as soon as possible. It can be detected as early as 20 days and as late as 40 days. Blood night HCG blood test is a more accurate way of pregnancy test, but mother can also use pregnancy test paper at home first.
Generally speaking, if menstruation is delayed for more than 7 days, you can consider doing an early pregnancy test to distinguish whether it is a "lucky pregnancy".
However, the termination of menstruation is not necessarily pregnancy, and the reasons for delaying menstruation may be gynecological diseases, excessive weight loss, psychotropic substances, drug hazards and so on. Therefore, whether menstrual regularity is only a way of discrimination is not a way of diagnosis.
It is incorrect to say that delayed menstruation means pregnancy.
What are the main manifestations of early pregnancy?
1, menstrual period terminated:
This is the most common sign of pregnancy. If a woman of marriageable childbearing age has normal menstruation and exceeds all normal physiological periods for half a month after sexual intercourse, she may be pregnant.
However, it's not that I didn't come during my menstrual period or I was pregnant. There are many reasons for not coming. It will be due to poor uterine and ovarian function, abnormal androgen, busy work and exam anxiety, which will all cause the delay of menstrual period.
So it is best to be diagnosed by a doctor before it is considered the safest.
2, chest tingling, swelling, itching:
There is tingling, swelling and itching in the chest, which is a physiological phenomenon in the early pregnancy. In addition, there will continue to be changes such as the darkening of areola, the protrusion of subcutaneous tissue arteries in the chest, and the protrusion of breasts.
3. Nausea, nausea and vomiting often occur:
Basically, many pregnant mothers in the first trimester often feel sick and want to vomit, especially at the beginning. This disease varies from person to person. Some people are very ill, while others are very ill.
Unless it is very strong nausea and vomiting, you must see a doctor, otherwise it is normal in the first trimester.
4, the color of the skin has changed:
Will it cause skin pigmentation or abdominal cavity to cause stretch marks, especially in the third trimester.
5, vaginal mucosa fading:
At the beginning of pregnancy, the vaginal mucosa will be darker because of hematoma, which is decided by the doctor.
6, very easy to fatigue:
Early pregnancy is very easy to fatigue, often sleepy.
7. Frequent urination:
In the third month of pregnancy, due to the expansion of the uterus, the size of the bra is reduced, and there will always be frequent urination.
How many days of pregnancy can be measured? In general, it can be measured from 7 days to 10 days. Of course, the later the test is conducted, the more accurate the result will be. Therefore, a woman can test whether she is pregnant or not after sleeping in the same bed for one week at the earliest and three weeks at the latest.
The detection time of different early pregnancy detection methods is different, and the detection time of early pregnancy directly depends on the selected early pregnancy detection method. The most common methods to detect early pregnancy mainly include early pregnancy test paper, blood HCG test, basal body temperature test and B-ultrasound test.
At the beginning of pregnancy, a series of symptoms will appear in women due to hormonal changes and pregnancy stimulation. Symptoms of early pregnancy generally include breast fullness, frequent urination, slight vaginal bleeding, menstrual stop, physical fatigue, dizziness, nausea and vomiting.
If a woman has these symptoms, she can be considered pregnant and needs further examination to confirm.
If you feel some of the above symptoms and pregnancy symptoms. At this time, wait for the arrival of menstruation and see what the result is. The possibility of pregnancy should be considered if the menstrual period exceeds 10 days.
There are several phenomena that can't detect pregnancy.
1, ectopic pregnancy
Ectopic pregnancy is not detected by early pregnancy test paper. As we all know, the main principle of early pregnancy test paper is to detect the HCG content in urine, and ectopic pregnancy is ectopic pregnancy, which means that fertilized eggs are not normally implanted into women's uterus, but implanted into fallopian tubes or ovaries and cervix.
The HCG value in the uterus is relatively low, so the HCG value in the urine is also very low, and the pregnancy test stick may not detect it!
If you find that you have a pregnancy reaction, but the pregnancy test stick can't detect pregnancy, you should pay attention to it and go to the hospital to confirm pregnancy in time to avoid some serious consequences!
2. Time problem
Some women are eager to have a pregnancy test after menstruation is postponed, but because of women's physical reasons, the menstrual cycle is not very accurate and the ovulation period is not very certain;
However, after sperm and eggs combine to form fertilized eggs, they are implanted into women's uterus. Although the pregnancy test stick claims that it can be detected on the first day of pregnancy, it can only be accurately detected after 7 days of implantation of fertilized eggs.
Therefore, the implantation time of fertilized eggs is too short to be detected. Another factor is that the HCG value of urine is different in the morning and afternoon. If the pregnancy is short, it is difficult to detect it in the afternoon. Don't worry, test it later!
3. The urine is too thin
Some treasure mothers are too nervous and drink a lot of water when preparing for pregnancy test, which leads to relatively diluted urine and more water in women's places;
The HCG content in fixed urine is relatively low, so the early pregnancy test paper may not be detected, so it is recommended not to drink too much water the day before the pregnancy test, so as not to affect the test results!
Generally speaking, the results of pregnancy test stick are very accurate, but because everyone's situation is different, the situation is different, and some people have low urine HCG value;
It takes a while to react, and a note may appear temporarily, and a second note will appear in a few minutes, so it's best to wait 10 minutes to know that you are pregnant!
