Occasional blood clots during menstruation are not a cause for concern. However, in some cases, it may be a sign of blood stasis. Blood stasis occurs when the blood flow becomes blocked or stagnant which leads to an accumulation of blood and clots.

This can result in heavy periods, pain, and other menstrual disorders. Both uterine fibroids and polyps have also been shown to lead to blood clots. Treatment with Chinese herbal supplements or acupuncture both have a long track record of success in resolving stasis thanks to their ability to improve circulation and increase blood flow to the uterus.

A light period that lasts for 10 or more days may be a sign of Qi deficiency. The light flow is an indication that the body is not able to retain blood. Kidney yang deficiency is also a known culprit. If a long, light flow is accompanied by coldness, pallor, and back or knee pain, this may indicate kidney yang deficiency.

A heavy period is not only inconvenient, but it may be associated with other unwelcome health issues such as anemia due to blood loss. Some common causes of a heavy flow include liver Qi stagnation, a poor diet, and chronic stress.

Possible Causes Why Your Period Won’t Stop

1. Hormonal Imbalance

Estrogen and progesterone are the key hormones that regulate a woman’s menstrual cycle. When these hormones are imbalanced, the uterine lining (endometrium) may become too thick or shed irregularly, leading to heavy bleeding or period that wont stop. Such imbalances are especially common in: 

• Polycystic ovary syndrome (PCOS)
• Thyroid disorders
• Sudden weight changes
• Stress or illness
• Certain hormonal contraceptives (like implants or IUDs)

A 2025 study found that women with menorrhagia had significantly higher follicle-stimulating hormone (FSH), estrogen, and testosterone levels, while prolactin was decreased compared to controls.

2. Fibroids 

Structural abnormalities of the uterus can also lead to period that wont stop. Uterine fibroids are growths that can affect uterine cavity, causing heavy or prolonged periods. A 2025 study highlights that uterine fibroids (leiomyomas) are the most common structural abnormality found in women with abnormal uterine bleeding (AUB), often causing persistent or heavy bleeding by distorting the uterine cavity.

3.Endometriosis

Endometriosis can be another cause, this is where tissue similar to the uterine lining grows outside the uterus, is another common condition associated with irregular or persistent bleeding. Endometriosis affects about 10% of women of reproductive age, it can lead to inflammation, anatomical abnormalities, and hormonal dysregulation that contribute to symptoms like heavy menstrual bleeding and pelvic pain

Lifestyle Changes

There are many simple lifestyle changes that can be implemented to bring regulatory back to the menstrual cycle. These include:

• Stress management: Since chronic stress is a known cause of long periods, practicing yoga or breathing exercises may help to provide needed relief.
• Diet: Those with a long period will want to include iron-rich foods such as meat and nutrient-packed fruits and vegetables.
• Exercise: Regular exercise will not only help with stress management, but it may also restore balance and normalcy to the menstrual cycle.
• Stay hydrated: Since menstrual fluids are high in water, it is important to stay properly hydrated.
