Perimenopause bleeding color varies but often appears darker, like brown or dark red, because hormonal shifts cause blood to stay in the uterus longer, oxidizing and darkening. You might also see bright red for fresh blood, or pink/light-colored discharge, especially during spotting between periods, which can be lighter and mixed with cervical fluid.
Cyclical brown blood may be a symptom of perimenopause. Dr Jennifer Grant, GP at Beacon HealthCheck, answers your medical questions each week in the Independent.ie.
“It's normal for people to skip periods, sometimes for several weeks or months, during perimenopause,” says OB/GYN Dr. Rebecca Jackson. What's not normal is having periods less than 21 days apart, experiencing bleeding or spotting in between periods or bleeding for more than 10 days.
Pink. Pink blood that is too thin to determine its texture often indicates low estrogen levels caused by hormonal birth control, significant weight loss, anemia, or a vitamin and mineral deficiency. Oftentimes, pink bleeding may also be accompanied by a cycle that only lasts about 3 days.
Key Takeaways. Bright red period blood is common at the start of your period and indicates blood has passed through your vagina quickly. Orange, gray, or green tinges in period blood can be signs of an STI or other infection.
Hormone imbalances are common in teenagers experiencing puberty or women entering menopause. This causes sporadic bleeding, heavy bleeding, or spotting. Many teenage girls have episodes of irregular bleeding during the first few months after their first menstrual period. This usually resolves without treatment.
This is the most common symptom of endometrial or uterine cancer. It may be hard to tell the difference between abnormal bleeding and your period, especially during perimenopause. Uterine cancer is uncommon in people younger than 45.
Very early perimenopause, when periods are still regular. Early menopause transition, from the onset of irregular periods. Late menopause transition, from the first cycle of more than 60 days. Late perimenopause, which is 12 months from your final period.
Symptoms to watch out for include: Having especially long or especially short menstrual periods that feel random and unpredictable. Changing menstrual products every hour for several hours in a row. Bleeding in between periods.
Your cycle can be harder to predict during perimenopause because your periods can become irregular as they start to wind down. But spotting isn't the same as when you get your period. The bleeding is usually lighter, so you don't generally need to reach for a pad or a tampon.
Period bleeding that is dark purple or blue in color, thick with clots, and that lasts longer than a week indicates high estrogen levels. In fact, high estrogen levels often cause symptoms associated with endometriosis, cysts, or fibroids.
Healthy period blood typically varies from bright red to dark brown or black. Blood or discharge that is orange or gray may indicate an infection. Women who experience bleeding during pregnancy should see a doctor or obstetrician for an evaluation.
Heavy menstrual bleeding during perimenopause can look different for everyone. Some people experience sudden, intense episodes of flooding, while others may have prolonged periods that seem to go on for weeks.
Postmenopausal bleeding can range from light spotting that is pinkish-gray or brown, all the way to a heavy flow, like a regular period. Most of the time, there is no pain with the bleeding. No matter your exact symptoms, you'll want to get in touch with your ob-gyn right away if this happens to you.
A flash period is your body getting off kilter
“Perimenopause is the Wild West for periods,” Minkin explained. “You could go months without one and suddenly bleed.” And you may not have any bloating, mood swings or cramping as warning signs because your body may not go through a full cycle.
The average length of perimenopause is about four years, but it can last up to eight years. Some people may only be in this stage for a few months, while others will be in this transition phase for several years.
During late perimenopause, menstrual cycles are much longer, sometimes over 60 days between periods. You may also notice an uptick in the intensity of other symptoms, such as hot flashes or night sweats, disrupted sleep, or vaginal dryness.
Many women benefit from seeing a gynecologist to manage perimenopause and menopause symptoms. Your gynecologist can order tests to check your hormone levels and analyze your blood and urine to rule out other health conditions unrelated to menopause.
Blood tests in perimenopause
In perimenopause, hormone blood tests such as FSH and estradiol are rarely reliable because levels fluctuate widely from day to day, meaning results can look “normal” even when symptoms clearly indicate hormonal change.
Irregular periods.
If you go 60 days or more between periods, you're likely in late perimenopause. If you go 12 months without a period and then start bleeding, talk to your healthcare professional right away. This could be a sign of a health issue.
Low estrogen during perimenopause causes hot flashes, night sweats, irregular periods, vaginal dryness, sleep problems, mood swings, brain fog, headaches, and joint aches, reflecting hormonal fluctuations affecting physical and mental health as the body transitions to menopause.
The biggest difference between spotting and your period is the amount of blood. A period can last for several days and require a tampon or pad to control your flow. However, spotting produces much less blood and doesn't typically require the use of these products.
Hormonal imbalances show up as symptoms like fatigue, mood swings, weight changes, irregular periods, skin issues (acne), hair changes, sleep problems, brain fog, low libido, digestive issues, and temperature sensitivity, affecting energy, body functions, and mental well-being, often linked to stress, thyroid, or reproductive hormones.
Bleeding can also cause shock, which may include any of the following symptoms:
