Black vaginal discharge instead of period

Black vaginal discharge instead of period is always alarming. Many women could experience black vaginal discharge before or after regular menstrual period but absence of menstrual flow combined with black discharge could be a symptom of several health conditions.

In many cases black vaginal discharge is a result of uterine cleaning from old oxidized menstrual blood or from remains of delayed period. It could happen during different days of menstrual cycle and it could be triggered by several factors. Actually female body expels this kind of coating as menstrual flow – monthly periods. If whole lining is not really eliminated throughout menstruation, this resides within the uterus until the following month.

Sometimes black vaginal discharge instead of period may be the indication of serious underlying disease such as cervical cancer, pelvic inflammatory disease, syphilis, Chlamydia, and some other sexually transmitted infections. But it should be mentioned that in cases of sexually transmitted infections women always mention, in addition, other disturbing symptoms including vaginal itching, unpleasant foul vaginal odor, burning sensations, frequent painful urination and discomfort or pain during intercourse.

Severe hormonal dysfunctions also could trigger black vaginal discharge instead of period. It could happen during polycystic ovarian diseases (PCOS), endometriosis, ovarian premature failure, hyperprolactinemia and sometimes during use of hormonal contraception such as birth control pills.

Black vaginal discharge instead of period – late period

If period is late because of hormonal deficit, it can appear with old cellular lining actually removed earlier together with old oxidized blood cellular material. If the entire lining is not expelled during normal regular menstrual cycle, it can be expelled along with blood cells during next late period. Actually female body expels old lining and oxidized blood instead of normal menstrual flow. In these cases, women experience black vaginal discharge instead of normal menstrual flow. In most cases black discharge instead of period is short (1-2 days).

Black vaginal discharge instead of period – implantation bleeding

Sometimes black vaginal discharge instead of period could be very early sign of pregnancy. This type of discharge called “implantation bleeding” which usually contains small amount of pinkish or brownish or black blood. Every third pregnant woman experience implantation bleeding. Why and how it is happening? It is well known that egg becomes fertilized by sperm during 12 hours after ovulation (usually in the outer portion of Fallopian tube) and then fertilized egg (zygote) travels down the Fallopian tube to the uterus. Cell division takes place during this journey and the zygote develops into an embryo. Inside the uterus, the fertilized egg (blastocyst) burrows into the uterine lining (on average about 9 days after ovulation – between 6 to 12 days past ovulation). Implantation bleeding appeared during implantation which causes damage of blood vessels in uterine lining. Implantation bleeding is far lighter than normal period and it doesn’t last for more than a couple of days.

Black vaginal discharge instead of period – birth control pills

Birth control pills are very popular not only for contraception but also for treatment of hormonal dysfunctions, acne, irregular periods and ovarian cysts. Birth control pills contain different combinations of estrogen and progesterone and they always inhibit ovulation, change general hormonal status, make the uterine lining inhospitable for implantation and change the structure of cervical mucus to make it difficult for sperm to pass by and find an egg. This is how birth control pills prevent pregnancy.

Birth control pills always suppress female hormones and sometimes super suppress hormones which could stop regular menstrual flow and cause black vaginal discharge instead of normal menstrual period.

Black vaginal discharge instead of period – pelvic inflammatory disease

Pelvic inflammatory disease (PID) is severe inflammation of reproductive organs (uterus, Fallopian tubes and ovaries). In most cases PID is triggered by sexually transmitted infections such as gonorrhea and Chlamydia. Women with intrauterine contraceptive device (IUD) have increased risks for PID.

Pelvic inflammatory disease may damage uterine lining and cause black vaginal discharge instead of period. In most cases women with PID also suffer from fever and chills, spread pain and tenderness in the lower abdomen, pelvic pain, increased smelly vaginal discharge, nausea and vomiting.

Black vaginal discharge instead of period – perimenopause

Perimenopause and following menopause are naturally occurring transition periods of women life. Perimenopause is the stage of women’s reproductive life that begins several years before menopause – it is time when ovarian functions slow down and the production of estrogen is gradually reduces. It is the period of natural shift from regular menstrual cycles to irregular menstrual cycles, anovulation and natural infertility. Usually perimenopause starts after 40 – the start and duration could be different in different women (depending on genetic and hormonal status). Decreased levels of hormones could cause black vaginal discharge instead of normal periods combined with hot flashes, night sweats, mood swings, sleep disruption, vaginal dryness.
