Pink Discharge Before Period – 10 Causes

Normally, vaginal discharge is either transparent or whitish. Pink discharge is associated with slight bleeding. It can be caused by three physiological and at least seven pathological factors. Discovering the etiology of pink discharge before period is vital for woman’s health, since pink discharge can accompany sexually transmitted diseases and even oncopathology.

Vaginal discharge between periods consists of cervical mucus, exfoliated necrotic cells of endothelium, which lines vaginal membrane from inside, and agents of normal microflora, which provide for the necessary level of рН in the secrete.

Normally, the discharge can be both transparent and thick white, which has do with cervical mucus production stages. If the discharge acquires light pink coloring, then it most probably points to the presence of a little amount of blood admixture. Since the peak of secretion of cervical mucus coincides with ovulation, which takes place approximately in the middle of the cycle, light pink vaginal discharge is observed approximately 2 weeks prior to the period.

The origin of pink discharge before period

We distinguish between 10 most common causes of a little amount of blood, present in the discharge between periods, namely:

  • Ovulation bleeding;
  • Implantation bleeding;
  • Adaptation bleeding, associated with the intake of hormonal birth control pills;
  • Hormonal disruption (polycystic ovarian syndrome, thyroid dysfunctions);
  • Sexuallytransmitteddiseases;
  • Cervical oncopathology;
  • Myomas, fybromyomas and other uterine neoplasms;
  • Endometriosis;
  • Adenomyosis;
  • Coagulation failure, including such, caused by the intake of certain drugs (for example, aspirin).

The first three points cover physiological causes of bleeding. Thus, ovulation bleeding can be explained by micro traumas, inflicted to the vessels in the process of the ovum’s emergence from the follicle. Implantation bleeding, in its turn, is provoked by affection of capillary tubes of the endometrium (uterine mucous lining) during the implantation of the fetus.

Bleeding, associated with the organism’s adjustment to hormonal contraceptives, is a variant of norm, as long as it persists for no more than 3-6 months. After this period, once quite natural reaction of the organism to the alteration of the hormonal profile, turns into a potentially dangerous symptom and possibly requires substitution of the selected drug or complete refusal of such a contraceptive means.

Pathological light pink vaginal discharge between periods

Endocrine diseases may be caused by occasional uterine bleeding of various intensity. In case the blood loss is insignificant and coincides with the active phase of cervical mucus production, the discharge will acquire pink coloring. Such a phenomenon can be observed at ovulation cycles and constitute one of the symptoms of infertility.

Sexually transmitted diseases (STDs) are able to provoke increased permeability of the vessels in the vaginal mucous lining. Besides, bleeding can be caused by erosions and cankers, which may appear under the influence of bacteria and viruses. In this case, the discharge may have unpleasant smell and dingy pink coloring, since it will be diluted not only with mucus but also with matter. Other common additional symptoms of STDs include itching and burning in genitalia.

Neoplastic (precancerous and cancerous) processes in the uterine cervix can be another cause for observing light pink bleeding between periods. Most frequently it is observed after intercourse.

Oncological diseases of the uterus are characterized by presence of bleeding out of the cycle. In case such a phenomenon overlaps with the peak of cervical mucus production, most probably pink discharge will be observed.

The same thing applies to endometriosis and adenomyosis, which are accompanied by light bleeding. Independently, these diseases are associated with irregular growth of endometrium. In the first case it proliferates out of the uterine cavity and in the second – it grows into the muscular layer.

Appearance of pink discharge before period, which has nothing to do with the cycle, and its reoccurrence for more than twice, serves ground for thorough examination. Some of the detected causes easily respond to correction, while the timely treatment of others can save the life of the patient.
