Many individuals have difficulty understanding what is considered “normal” regarding their menstrual cycle and when they should seek testing for unexpected bleeding that occurs between regular menstrual cycles. Approximately one-third of women report that they have experienced unexpected bleeding during their monthly cycle due to hormonal imbalance, stress, or infection (including sexually transmitted diseases). Understanding the differences between what constitutes abnormal and when to seek the necessary tests can aid any individual in maintaining and protecting their reproductive health before a small issue develops into a potentially larger problem.
What is spotting between periods?
Spotting is defined as light vaginal bleeding outside of the individual’s normal menstrual cycle. Symptoms of spotting may include blood drops on underwear, very light pink or brown discharge, or very light bleeding that does not require the need to use a sanitary napkin or tampon. Spotting occurs at various times during a menstrual cycle, including before the beginning of a person’s menstrual cycle, after the completion of their monthly cycle, or randomly at any other time.
Spotting between menstrual cycles can be considered a minor health issue for many people; however, frequent or unknown spotting between menstrual cycles should always be considered a health priority and be investigated further if associated with additional symptoms or complaints by the individual.
What is considered a normal menstrual pattern?
What is a normal menstrual pattern?
The average menstrual cycle lasts approximately 21 to 35 days, with a bleeding duration of around two to seven days. There are many reasons why a cycle can be totally unpredictable or fluctuate in time or quantity of blood flow on a monthly basis, including hormones.
There are many variables in everyday living that may affect one’s menstrual cycle; stress, changes in sleep habits, dietary or weight changes, rigorous exercise routines, and medications, to name a few. Other common life occurrences include traveling or dealing with an emotional crisis; both of these situations can interrupt normal hormone production temporarily.
Therefore, experiencing spotting occasionally does not mean something is wrong; identifying if a pattern exists and placing it within context are very important.
When spotting becomes a concern
Spotting should be of concern if it becomes:
- Frequent, persistent
- Associated with discomfort or pain
- After having sexual intercourse
- Accompanied by abnormal vaginal discharge or os smell
- Along with pelvic pain or urinary symptoms.
When experiencing spotting along with any of the above, also consider possible infections, including sexually transmitted infections (STIs).
Can STIs cause spotting between periods?
Yes, there are several different types of STIs or other bacteria or viruses that can cause irritation to the reproductive tract, causing inflammation, tenderness of the tissue in the area, and abnormal bleeding. Abnormal bleeding may manifest itself as spotting between menstrual cycles or as uterine bleeding following sexual intercourse. Further, because STIs may affect the cervix directly, which is an area of great sensitivity and is very easily irritated by either inflammation or infection, there is a direct correlation between STIs and abnormal bleeding.
Now, let’s look at additional potential causes of abnormal/irregular bleeding associated with several of the most commonly diagnosed STIs.
Chlamydia and Gonorrhea
Cervical inflammation can be caused by two of the most widespread bacterial STIs: chlamydia and gonorrhea. There is a greater likelihood of bleeding (especially during and after sexual intercourse) when the cervix has become inflamed.
Chlamydia and gonorrhea often develop without symptoms until they have created complications; therefore, many people remain unaware they are infected. Both chlamydia and gonorrhea can produce symptoms once they have progressed sufficiently, including spotting, discomfort in the pelvis, and an abnormal discharge.
Chlamydia and gonorrhea can also spread to deeper structures of the reproductive tract if left untreated, resulting in the development of pelvic inflammatory disease (PID) which can impact fertility.
Trichomoniasis
Trichomoniasis is a parasite that can irritate the tissues of the vagina (vaginal tissue irritation can sometimes lead to light bleeding).
Trichomoniasis can result in discomfort when urinating, as well as itching and an increase in discharge due to irritation. Additionally, the vaginal lining is affected, meaning light friction may create spotting.
Bacterial Vaginosis (BV)
BV is not classified as an STI but is often associated with sexual intercourse and has been linked to an increased risk of other sexually transmitted infections.
BV occurs when there is a disturbance of the natural balance of bacteria present in the vagina. BV itself does not directly cause significant bleeding; however, the irritation and sensitivity to tissue generated by BV can occasionally result in light bleeding.
BV is frequently indicated by strong or malodorous discharge in the vagina.
Genital Herpes
Considerable amounts of blisters or ulcers form within the genital and vaginal region caused by Genital Herpes. Ruptured sores result in mild/restrictive bleeding as well.
Symptoms are often accompanied by an array of debilitating symptoms such as pain, itchiness, or burning; however, others may experience such minor clinical signs that they would be entirely unaware that they even have the disease.
Human Papillomavirus (HPV)
Human Papilloma Virus (HPV) produces a multitude of virus-related disease entities and is one of the most predominant viral infections globally. A great number of cases resolve spontaneously, but high-risk HPV strains have a propensity to create cellular changes of the cervical tissue.
An important related symptom of cervical tissue changes is abnormal vaginal bleeding, which can occur as bleeding between menstrual cycles or occurring after sexual intercourse.
Cervical cancer is commonly associated with long-term (>5yrs) untreated, high-risk HPV strains and can have a clinical presentation of irregular bleeding.
Syphilis
Syphilis causes sores (chancres) that are typically painless and can occur inside the vagina or on the cervix, thereby causing mild irritation or very light bleeding if present.
While the sores would cause mild/restrictive bleeding, the affected tissues become more acutely sensitive to any form of trauma resulting in possible spontaneous bleeding from that tissue.
Symptoms that suggest an STI-related cause
Just because there is spotting does not mean there is an STI. However, if you also have other symptoms with it, your risk goes up.
Some symptoms to watch for if you suspect you may have an STI are:
- Pain or burning when urinating
- Pain during intercourse
- Unusual vaginal discharge (change in color, sign, or texture)
- Pain in the pelvis or lower abdomen
- Itching, irritation, or soreness around the genitals
- Sores, bumps, or other wounds on the genitals
- Flu-like symptoms such as fatigue and low-grade fever
It is also important to note that many STIs do not show any signs at all during the early phase, which is why routine testing for STIs is so important.
Other possible causes of spotting
Besides an STI, there are many reasons why there may be spotting or bleeding between periods. More frequently than an STI, there are non-infectious things that can cause spotting of this nature.
Many women who begin using hormonal birth control experience breakthrough bleeding during the first few months after they start using the birth control method. Women who have used emergency contraception are also likely to see irregularities in their cycles due to this method of birth control.
Hormonal fluctuations caused by being stressed, weight changes, thyroid disruption, or conditions like PCOS can all result in changes to the menstrual cycle.
Other physical causes of spotting can include vaginal dryness or minor injury during sexual intercourse.
Also, structural problems such as polyps or fibroid tumors may also be responsible for bleeding or spotting.
When you should suspect an STI
When you have unusual spotting between periods, you should be suspecting an STI. Consider testing for STIs if spotting occurs:
- For the first time or whenever it’s unclear what’s causing it
- After having or performing any sexual activity
- With pelvic cramps, any change to your normal discharge, or any combination of them
- With a history of multiple sexual partners or unprotected sexual encounters
- Repeating every month with no explanation from hormone levels
The chance of something being wrong is even higher if you’ve had bleeding after having sexual intercourse, as the cervix commonly has infections like Chlamydia and HPV.
Why early testing matters
Getting tested for STIs early is important. Most STIs are easy to treat, however the risk of complications from delaying diagnosis increases with time.
The Importance of Testing Early
One of the hardest parts about getting tested for STIs is that many don’t have symptoms. You may not notice anything is wrong while the infection slowly develops.
If left untreated, an STI such as Chlamydia or Gonorrhea can make its way into the upper reproductive tract and can lead to Pelvic Inflammatory Disease (PID). PID can result in long-lasting pelvic pain, infertility, or complications with any future pregnancies.
On the upside, most STIs are very treatable once diagnosed. As long as the infection is caught early enough, there will be numerous antibiotic or antiviral options available that can eradicate the infection.
