How many days after conception can the test be detected? What should be paid attention to during conception?

Today, the editor is here to share some scientific knowledge~ Many mothers can feel that they are pregnant, but they don’t understand how conception actually occurs. How many days after conception can it be detected? What should you pay attention to during pregnancy? The answers are all in the article~

What is the conception process like?

The combination of sperm and egg is called conception or fertilization. The conception process is: during sexual intercourse, the man ejaculates semen into the woman's vagina, and the sperm relies on the tail to swing towards the uterus and then enter the fallopian tube. Each time a man ejaculates semen, there are hundreds of millions of sperm, but most of the sperm lose their vitality or die in the acidic environment of the vagina, and only a very small number of sperm can overcome many obstacles and reach the fallopian tube. The time it takes for sperm to reach the fallopian tube from the vagina is only a few minutes at the fastest, and generally takes 1-1.5 hours. These sperm that reach the fallopian tube lose their ability to conceive after 3 days. During the childbearing age, women's ovaries release a mature egg every month, and after the egg is released, it is captured by the fallopian tube umbrella and enters the fallopian tube. Within 24 hours after the egg is released, if it encounters sperm in the fallopian tube, the egg will be surrounded by a group of sperm, and only one sperm can drill into the egg for fertilization. The fertilized egg is a fertilized egg. The fertilized egg develops in the fallopian tube and gradually moves towards the uterine cavity. About 7-8 days after fertilization, it reaches the uterine cavity and implants into the endometrium, where it continuously absorbs nutrients and gradually develops into a mature fetus.

How many days can pregnancy be detected?

For most people, it usually takes about 10-12 days from fertilization to implantation of the fertilized egg to the detection of pregnancy test paper, but there are some special cases. On the Internet, some mothers said that they could detect it in 7 days when they were showing off their pregnancy. From a scientific point of view, this is also possible.

Before implantation, the fertilized egg has no connection with the mother, so we have no way of knowing its existence. After implantation, the outer trophoblast cells of the fertilized egg produce a protease to dissolve the endometrium in contact with it, and the fertilized egg is buried in the functional layer of the endometrium. At this time, the syncytial trophoblast will develop and extend many cell protrusions, which are uniformly villi, called villi. Therefore, the hormone it secretes has a very strange name - human chorionic gonadotropin (HCG). Now, we can more accurately calculate how many days after AA we can detect the existence of this hormone!

After fertilization, the egg takes 4-5 days to travel from the fallopian tube to the uterus and stays in the uterine cavity for 3-4 days. This process takes a total of 7-9 days. Therefore, if you use an early pregnancy diagnosis kit with a higher sensitivity (15 international units), it is very normal and reasonable to detect HCG about 7 days after ovulation; if you use a general early pregnancy test strip (25 international units), it is about 12 days after ovulation.

Don't get pregnant during these 9 periods

1. Avoid getting pregnant after recent emotional fluctuations or mental trauma (great joy, wedding night; great sorrow, loss of a loved one; unexpected work-related injury, etc.).

2. Avoid excessive smoking and drinking. It is not advisable to conceive immediately after smoking or drinking.

3. Avoid getting pregnant within 6 months of recovery time after reproductive organ surgery (diagnostic curettage, artificial abortion, intrauterine contraceptive device insertion or removal, etc.).

4. Avoid getting pregnant before 6 months of recovery from childbirth to avoid affecting your physical recovery.

5. Avoid getting pregnant right after being exposed to toxic substances (for example, pesticides, lead, mercury, cadmium, anesthetics, etc.).

6. Avoid X-ray exposure, radiation therapy, viral infection or medication for chronic diseases, and do not conceive within 3 months of stopping medication.

7. Avoid pregnancy within 3 months of stopping oral or implantable contraceptives. It is reported that contraceptives have a certain effect on the chromosomes of somatic cells because they can increase the frequency of sister chromatid exchanges in somatic cells.

8. Avoid long-distance business trips, as you may get pregnant within two weeks after returning home exhausted.

9. Avoid getting pregnant during extremely cold or hot weather, or during heavy rain or thunder, because lightning can produce extremely strong radiation that can cause chromosome aberrations in reproductive cells.
