Can You Feel Implantation? Implantation Symptoms

Bleeding is the only sensible consequence of implantation. It is identified as an important perceivable symptom and sensation after implantation.

Peak increase in the basal body temperature on the relevant diagram can be another indicator of the implantation process. The veracity of such symptoms, as dragging abdominal pain, queasiness, metallic aftertaste, and many others, which experienced mothers colorfully describe to women who have never had children, are not verified. They fall into the category of psychosomatic phenomena.

Implantation is the process of the fertilized egg’s attachment to the uterine wall, specifically to its endometrium. It takes place in 3 stages – ovum’s germination into the mucous lining, adjustment of the endometrium to pregnancy (decidualization) and immunological perception.

Implantation is the process of the fertilized egg’s attachment to the uterine wall, specifically to its endometrium. It takes place in 3 stages – ovum’s germination into the mucous lining, adjustment of the endometrium to pregnancy (decidualization) and immunological perception.

On the initial stage, the cycling cell produces various bioactive substances and provokes modifications in the woman’s endocrine profile. Specifically, the dissolving secretions of the embryo cause affection of the upper layer of endometrium (epithelium), and it becomes possible for the cell to attach itself directly to the underlying mucous membrane. At first the fetus adheres to it (adhesion), then it gets fixed and only after this it invades the stroma (invasion).

During this process, mother’s organism secretes 2 types of substances. The first ones are protectors for the deeper layers of the uterus – they prevent the ovum from too deep invasion. The second ones help the embryo – prepare the endometrium, ensure its protection from immune cells.

How does the invasion of the embryo cells take place?

Fertilization of the ovum with the sperm cell occurs in the fallopian tube and it takes only a few minutes or hours at most, and follows the ovum’s detachment from the ovary (ovulation). It is on the sixth day after this, that the implantation process begins.

The developing embryo “adheres” to the erosion area, deliberately formed on the surface of the endumetrium. Naturally, it results in the origination of an edema around the implantation spot. Apart from this, the uterine walls vasculature begin to expand radically – blood circulation improves, rambling glands become more active and secrete increased amounts of mucus and nutrients.

On the 9-10 day the fetus deeper invades the mucous membrane, and on the 11-12 day it completely disappears in its thickness. The newly formed epithelium covers the affected tissue, and only a small prominence, towards the uterine cavity, gives away the little secret.

The adherence is usually completed by the 13th day, however, it is sometimes possible to have little bleeding from the invasion area. It is identified as an important perceivable symptom and sensation after implantation. Other subjective sensations are the consequence of heightened impressiveness of the woman and her desire to track the moment, when the pregnancy actually began.

Back to implantation bleeding

It occurs on the 28th day of the menstrual cycle and might look very much like little menstrual discharge that comes ahead of time. Implantation bleeding is not a wide spread phenomenon. However, if the period ended too soon and instead of usual bleeding there was just pink or light brownish spotting, then occurrence of pregnancy can be presumed. However, pregnancy can only be confirmed through laboratory texting and heartbeat sonography.

Among the reasons, which cause such bleeding, are

  • Taking hormonal contraceptives;
  • Sexually transmitted diseases;
  • Chronic inflammatory processes;
  • Cervical erosion;
  • Blastomas.

Therefore, in case the period gave you some doubts, it would be better to see your doctor, all the more so, as there are dangerous types of bleeding in the first trimester of pregnancy. In particular, you should see a doctor in case you see profuse and/or purple discharge, or experience nausea, faintness and deterioration of general well-being.

Specific reformation of the endometrium

The second stage of implantation is about endometrium’s accommodation to the further course of pregnancy and it is called decidualization.

In fact, it is the natural reaction to the increase in progesterone level, which takes place after ovulation.

Implantation is the result of complex interaction between the fetus and the endometrium. In order for the implantation to take place, certain conditions should be met:

  • Endometrium thickness should reach up to 1.3cm:
  • The mucous membrane cells should contain sufficient amount of trophic substances;
  • The level of progesterone should be sufficiently high.

From one side the decidual tissue takes the ovum, and from the other side it performs the function of a protective layer, which prevents the underlying layers from being affected by the aggressively invasive embryo.

In the area where the endometrium is affected (after endometritis, caesarean section or abortion), decudialaization is being disturbed, which causes pathological placenta in-growth.

Implantation can be prevented not only by endometrium pathologies, but also ovum deficiencies, such as a too thick pellucid zone. Such a modification of ovules is typical to women after 40 years of age.

What is the role of immune protection?

As 50% of genes of the implanted embryo are of father’s origin, it appears to be semi-enthetic for the woman. Its detachment is prevented by the production of specific factors, which suppress aggressive reaction by the immune system.

Another important factor is the ability of the endometrium cells to “scan” the embryo. In fact, the cycling ovum stays in the uterus for a few days before implantation. Anomalous fetuses are detected and “expelled” from the mother’s womb. This is how the “prenatal filters” work.

It is supposed that up to 50% of pregnancies are being interrupted in this manner. There is no accurate statistic data available, as in terms of the time of its occurrence, such a rejection can only be slightly different from a regular period (a bit late) and not be taken into account by the woman, due to being almost identical to menstruation.

In case of in vitro fertilization (IVF), the important function of the intrauterine selection is not left to the nature alone. Instead, pre-implantation screening is conducted, for which a micro-part of the protembryo is taken for the investigation of its DNA.

Anomalous implantation

Unfortunately, endometrium is not the only tissue, into which the “buoyant” fetus can be implanted. Its attachment to the mucous fallopian tube, ovary or abdominal cavity organs result in ectopic (extrauterine) pregnancy. This is a serious pathological form of pregnancy, which exposes the woman’s health and life to a great risk.

Another, not less dangerous variety of an abnormal implantation is the hydiatiform mole. This pathology develops due to the invasion of an ovum, which might or might not contain an anomalous embryo. Therefore, experiencing menstrual disorders or having a positive pregnancy test after unprotected intercourse, it is best advisable to see your doctor and ascertain the presence and proper course of pregnancy.

Objective symptoms, that help to feel implantation

Implantation is one of the critical periods of pregnancy. Only the balance of all the hormonal factors can ensure its maintenance. It might not take place due to a genetic error, endometrial insufficiency, thickness of the ovular coat, as well as congenital abnormalities.

Embryo’s implantation into the endometrium is not accompanied by proven sensations, but it can be traced on the basal body temperature diagram, which some women follow. The body temperature rises, which is indicative to implantation. Other “signs”, such as irritability, taste disturbance or swollen breasts refer to early pregnancy symptoms, and might testify to implantation somewhat post factum.
