Sensations and signs during embryo implantation
Implantation is the process of introducing a fertilized egg into the endometrium of the uterus. If this process goes away with violations or does not take place at all, the pregnancy will not come. Therefore, women who have been waiting for and planning a pregnancy for a long time are trying to catch the subtlest nuances of sensations in order to understand whether this has happened or not.
Timing and process
Conception happened. But this is not enough. It is necessary that the fertilized egg successfully reached from the fallopian tube, where the meeting with the spermatozoid took place, to the uterine cavity, where the baby will have to grow and develop throughout the pregnancy. In this way, the zygote, which turned into an oocyte after fertilization, is sent in the first day after conception, and it usually takes from 3 to 5 days.
Then another 1-2 days, and sometimes longer the fertilized egg is in free swimming in the uterus. It feeds on those beneficial substances that are contained in the uterine fluid, and patiently waits until it is nailed to the wall of the uterus.
If this does not happen, in 4-5 days the fertilized egg will die and come out together with the next menstruation, the woman may not even guess that she was "almost pregnant."
The zygote goes through the morula stage and becomes a blastocyst. It has two shells. The internal will then become the basis for the formation of the internal organs of the child, and the external will be responsible for the implantation process, and then for the formation of the placenta.
The blastocyst sticks to the wall of the uterus. From this moment implantation begins. Average time - 7-8 days after ovulation. But there is a later or earlier implantation. The process of introducing the blastocyst into the uterine wall lasts about 40 hours.
Clinging to the endometrium, the outer layer of the blastocyst is transformed into thin hairs, the conductors. At first, they produce enzyme substances that dissolve endometrial cells. In the resulting space, the fetal egg digs as deep as possible. Then the villi unite with the blood vessels and form the chorion.
At the end of the implantation, the embryo begins to receive nutrients from the maternal blood.
Pregnancy has come, but a woman will know about it only when a sufficient amount of a special hormone produced by the cells of the chorion, hCG, accumulates in the blood and urine.
This will happen immediately before or immediately after the delay of menstruation, that is, about a week after implantation.
Feelings and signs
Officially, in medicine, it is believed that a woman does not experience any special signs and sensations during implantation. The process is so microscopic, cellular, that to feel at least something is almost impossible. However, the feedback from women clearly shows that many managed to feel the implantation, and for a number of future moms it was quite painful.
Not everyone feels the implantation. It depends on individual sensitivity, primarily on changes in hormonal levels.
Most often, women describe their feelings like this:
- little loin aches a bit, as before menstruation (but up to menstruation is about a week, and therefore very few people pay attention to these weak, barely noticeable pains);
- the lower abdomen may hurt, but there is no severe pain, only minor aching discomfort that lasts for about two days and passes;
- the temperature rises slightly (not higher than 37.0 with a little, and therefore a woman may not pay attention to this either);
- a headache, a sore throat, a cough and chills appear - immunity during implantation decreases sharply to give a chance for the egg to not be rejected by vigilant immune cells, and usually women perceive these feelings as a signal that they have simply caught a cold or caught a virus;
- drowsiness increases, a woman feels overwhelmed, tired, a slight anxious feeling may appear;
- many say that they felt a faint metallic taste in their mouth - the medicine does not know how to explain it.
Only the so-called implant bleeding can be attributed to more or less reliable signs.
In the process of introducing the ovum into the endometrial layer, the enzymes dissolve the cells of the inner lining of the uterus, and the released blood can go outside. There is little blood, because it is not the veins or arteries that are damaged, but the smallest blood vessels of the human body - the capillaries.
Usually, women react with bewilderment - before the menstruation there is still a week, or even more, and blame the appearance of bloody spotting on a failure in the cycle. but implantational discharge has nothing to do with menstruation, and within a day there is no trace of them.
Such a sign does not appear in all women, and therefore you should not rely on it as an early diagnosis of pregnancy. This is one of the medical mysteries, which scientists still could not explain the mechanisms.
Only one thing is known for certain - such bleeding does not in any way affect the development of the fetus, the state of the mother, or the pregnancy itself, nor does it affect the course of labor.
If a woman measures basal temperature regularly, then at 40 hours of implantation she can pay attention to the rise of the thermometer to 37.4-37.5 degrees.
If the temperature is higher and there is pain, then we are talking about the inflammatory process, and not about the implantation of the embryo.
The hCG level rises every two days, doubling its values. That is why, theoretically, and again, not everybody already after 4-6 days a woman can have the first changes in her body and well-being, caused by a change in the balance of hormones.
These symptoms may include mild nausea, dizziness, bouts of weakness, increased fatigue, temperature rise in the evening to subfebrile values. Many women describe that in these terms they began to drastically change their mood - from sadness to joy, from annoyance to anger. Also, women say that they became more sentimental and somehow they were especially concerned with the touching photos of babies, kittens, puppies and other “milots”, if they met them on the Internet.
Useful tips
If a woman really wants to get pregnant and seeks out every day after ovulation signs of pregnancy, she is under stress. In this state, stress hormones are produced - adrenaline and cortisone. They partially block the production of sex hormones.
Implantation may not take place due to reduced levels of progesterone. And because the best that can be advised - relax. Thus, you will increase the chances of successful implantation.
It is noteworthy that reducing weight before conception increases the likelihood of implantation by almost 45%. To do this, it is enough to lose only 5% of body weight with excess weight. Also, a woman who is expecting a pregnancy as a miracle is not advised to drink coffee - caffeine negatively affects the level of sex hormones.
Experts advise women, suggesting that they could become pregnant, in the second half of the menstrual cycle to use more foods with a high content of protein - meat, fish, dairy products. It also increases the likelihood of successful implantation of the ovum into the uterine wall.
