The topic of pregnancy is always relevant for women of reproductive age.
In order to learn about the special situation as early as possible, they begin to listen to unique changes in their own organism.
Signs of pregnancy are known (toxemia, bleeding, mood swings, diarrhea) to many. But they do not appear at a time.
For each symptom, there is a certain period when its manifestation becomes noticeable. It is important to know these terms.
The nuances of physiology: how many days are needed for conception?
In the human body there are two main types of cells – sex and somatic. Germ cells (eggs and sperm) are able to give rise to a new life.
In the middle of the menstrual cycle in the female body, ovulation occurs when an already mature egg is sent to free swimming.
“Meeting” of male and female germ cells occurs in the fallopian tube. After the eruption of seminal fluid sperm for some time moving through the female genital tract.
They surround the mature ovule, after which one or more sperm (in rare cases) penetrate it. The surface of the female reproductive cell closes, preventing further penetration of sperm.
Approximately 12-14 hours after fertilization, the cell nuclei reorganize, converge and form a single-cell embryo.
It constantly moves along the fallopian tube and in the process is divided into two parts – a large one (the body of the unborn child) and a small one (the placental membrane). Further embryo formation continues in the uterine lining.
Egg implantation: how long the embryo moves to the uterus
The movement of the egg through the fallopian tubes begins immediately after fertilization. This path usually takes from 7 to 12 days, and on average about ten.
The duration of movement through the fallopian tubes is influenced by many factors, including their length.
Full cell development requires nutrition. Attaching to the endometrium of the uterus occurs when it is necessary to replenish the supply of nutrients.
Usually the implantation process takes no more than two days. It is fully completed when the fertilized egg is finally immersed in the uterine epithelium. Then, hormone production is stimulated, as a result of which the very first signs of pregnancy appear.
This period will be taken as a reference. Most often, the embryo is introduced 9–10 days after fertilization.
But depending on the individual characteristics of the female body, the periods can be shifted by 1-6 days in a smaller or larger direction. It turns out that implantation can occur at 8-14 days after fertilization of the egg.
When signs of pregnancy appear
For the first trimester of pregnancy is characterized by the manifestation of specific symptoms such as:
They can appear a certain number of days after the alleged conception.
This selection of bloody type, which are scarce and plentiful, depending on the physiological characteristics of the female body.
It manifests itself 8-10 days after fertilization, when the embryo attaches to the wall of the uterus. This is one of the important signs of pregnancy.
- Slight uterine pain pulling character.
The pains are triggered by the process of embryo landing on the uterine epithelium.
At 8-10 days after the alleged conception, slight pain in the lower abdomen may occur.
This is a standard phenomenon, but in case of an increase, you should consult a doctor to avoid abortion.
Observed at 8-10 day after conception.
- Increase in basal temperature.
The basal temperature is measured rectally in the morning, immediately after waking up.
At the time of attachment of the egg basal temperature drops to 36.8-36.9 ° C. This is due to a sharp increase in estrogen in a woman’s body.
After implantation of the ovum basal temperature rises again above 37.1 ° C and remains at this level until 14-16 weeks of pregnancy.
Then the rectal temperature drops to 36.8-36.9 ° C.
Increased sensitivity of the mammary glands may occur in the first or second week after the putative conception (7-14 days).
Changes in hormonal levels lead to such manifestations.
In some pregnant women, swelling and chest pain occur only 20-30 days after fertilization of the egg.
- Mood swings.
Depression, alternating with joy, is also caused by a hormonal surge. Usually manifest at 10-14 days after pregnancy.
Human chorionic gonadotropin in the blood is usually determined as early as 9-12 days after the conception of the child.
- The second strip on the test.
Many women use special tests to confirm their “interesting” position.
It determines the amount of the hormone HCG, the level of which in the urine does not appear immediately, but only on the 11-14 day after the expected date of conception.
- Diarrhea and other disorders of the gastrointestinal tract.
Heartburn, bloating, flatulence, diarrhea – these are the characteristic signs of pregnancy that can occur on the 14th-20th day after presumptive fertilization.
This is one of the main signs of the imminent birth of a child.
Usually toxicosis occurs 5-7 weeks after fertilization of the egg.
- Fatigue, drowsiness, dizziness.
These are important signs of a particular condition of the female body. The reason lies in a sharp drop in blood pressure.
2-3 weeks after the alleged conception, some women may start to lose consciousness periodically.
But this phenomenon is considered normal.
Conception is a complex physiological process that goes through several stages. The result is fertilization of the egg and the formation of an embryo, which continues to develop in the uterus until the onset of labor.
Determine pregnancy can be on numerous grounds, manifested in the first trimester. But for each symptom is characterized by certain periods of manifestation. All the above signs are quite specific and appear only after 2-14 days after conception.
