Spotting a Week After Ovulation. The First Symptom of Impregnation

Spotting a week after ovulation can be indicative to implantation. Implantation bleeding (IB) can be distinguished through the following characteristic features:

  1. It starts on the 6th -7th day after conception and lasts no more than 3-4 days;
  2. It is scanty;
  3. and painless.

All other types of bloody discharge, particularly intensive and reoccurring types, point to certain pathologies and require clinical examination.

Immergence of the ovum from the follicle takes place in the middle of a normal menstrual cycle. After ovulation, the ovum travels down into the uterine tube, where it starts its way to the uterine cavity, drawn by endometrial ciliae. During the next 24 hours it is ready for fertilization. In case conception takes place successfully, the zygote (ovum + sperm cell) starts fissioning and preparing to the implantation process, which occurs on the sixth day after ovulation.

Implantation bleeding – physiological spotting after ovulation

Implantation involves three stages: adhesion, fixation and invasion of the embryo into the thickness of the mucous lining (endometrium). The last stage becomes possible after the affection of the mucous lining with the help of bioactive dissolving substances, which are produced by a special layer of the embryo, namely trophoblast cells. This affected area of endometrial surface is the place, to which the fertilized egg adheres and then invades.

This process can normally be accompanied by disturbance of integrity of capillary walls, and consequently lead to scanty uterine bleeding a week after ovulation. In order to have sufficient ground to consider this spotting as implantation bleeding it is required to pay attention to the following 3 factors:

  1. Time when such bleeding occurs and its persistence;
  2. The way it looks;
  3. Concomitant symptoms.

In case bleeding was observed on the 6th -7th day after ovulation and last no more than 3-4 days, it can quite possibly be induced by ovulation. This case has to do with the circumstance that having started the process of invasion following a week after fertilization, the fetus rather deeply grows into the mucous lining on the 9th -10th day. On the 11th-12th day after conception, the erosion, through which it had penetrated into the mucous lining, heals almost completely.

IB is usually rather scant – from a few drops on the underwear to brown spotting lasting a few days. Sometimes the discharge has a light-pink tinge, which is associated with a little amount of blood, lavishly diluted in cervical mucus, which is still being produced under the influence of “hormonal firework”, which accompanies early stages of pregnancy.

Implantation takes place on the cellular layer, that is why it is impossible to feel it. It is required to seek medical help if bloody discharge after ovulation goes in line with acute cramps, headache or rise of body temperature. Implantation does not involve any such symptoms. Instead, it may cause sickness, taste disturbance, drowsiness, frequency of urination. All these early pregnancy signs can be observed immediately after IB.

Other causes of vaginal bleeding a week after ovulation

Irregular bloody discharge between periods is commonly referred to as metrorrhagia. It can appear at any stage of the cycle, including after ovulation. Metrorrhagia is classified into 2 types, namely acute and chronic. The first type, accordingly, can appear unexpectedly, being induced by a trauma, disturbance of the course of pregnancy, coagulation disorders (for example, caused by the intake of a certain drug), cervical or endometrial cycle, etc.

Chronic spotting out of cycle can be associated with:

  • Nonmalignant diseases of the uterus (Fibromyomas);
  • Endometriosis (pathological proliferation of the endometrial layer out of the uterine cavity);
  • Cervical polyps;
  • Ovarian polycystic syndrome;
  • Dysfunctional uterine bleeding of unknown genesis;
  • System diseases (such as thyroid disorders), etc.

Besides, blood can appear in pathological discharge in case of sexually transmitted diseases. In any case, it is possible to distinguish IB from such conditions, following the mentioned differentiating factors. Acute and/or reoccurring bloody discharge, especially in combination with other symptoms, constitute signs of pathology.
