Should You Worry About Blood Clots During Your Period?

Have you ever noticed blood clots and wondered if these changes are considered normal? While seeing clots can feel concerning, they are a part of your normal biological process. In many cases, small clots form when menstrual blood collects in the uterus or vagina before being released. In some cases, heavy periods with blood clots may occur alongside other symptoms. 

Conditions such as endometriosis, fibroids, hormonal imbalances and perimenopause could lead to troubles such as heavy menstrual bleeding. Understanding the difference between normal and abnormal period clots can help you understand if a further assessment is required. Through this blog, we’ll try to understand the meaning, causes, and signs that indicate a need for medical attention. 

A] What Are Period Blood Clots?

Period blood clots are collections of blood, tissue, and fragments of the uterine lining. This occurs when menstrual blood collects inside the uterus or vagina. This is particularly common during the heaviest days of your period. Clots with a dark red or bright red appearance are often considered normal during heavy flow days. Brownish clots are more noticeable towards the end of your period. It is large clots during periods that are accompanied by severe pain that you need to be aware of. This is because they often indicate an underlying gynaecological condition.

B] What Do Healthy Period Clots Look Like?

Healthy menstrual clots are typically small in size. They could appear occasionally rather than continuously throughout your period. They could have a jelly-like consistency with a dark red or bright red colour. There could even be certain variations influenced by the amount of bleeding. Clots larger than a coin could point towards your menstrual flow being excessively heavy. Understanding what healthy menstrual clots look like can definitely help you feel more confident. 

C] What Conditions Lead To Heavy Menstrual Bleeding With Clots?

Conditions such as hormonal imbalance, fibroids, endometriosis, and perimenopause are among the common causes for heavy menstrual bleeding with clots. Understanding these conditions can provide valuable insight into your reproductive health. 

1. Hormonal Imbalances

Your cycle is mainly regulated by reproductive hormones such as oestrogen and progesterone. When these become disrupted, your cycle might also become irregular. With irregular ovulation, your progesterone levels might become insufficient when compared with oestrogen levels. Ovulatory dysfunction could also result in excessive endometrial thickening and episodes of abnormal heavy bleeding. 

2. Fibroids

Uterine fibroids are common non-cancerous growths that are among the leading causes of heavy menstrual bleeding with clots. These abnormalities might interfere with your uterus’s ability to contract and regulate menstrual flow effectively. These can increase the amount of tissue and blood being shed during menstruation. This can lead to prolonged bleeding, pelvic discomfort or worsening menstrual pain.

3. Endometriosis

Endometriosis is a chronic gynaecological condition in which the endometrial-like tissue grows outside the uterus. Unlike menstrual blood, this tissue cannot leave the body normally. This is commonly known to affect the ovaries, fallopian tubes, pelvic lining, bladder or surrounding pelvic structures. Even if endometriosis is mostly associated with pain, it can also contribute to heavy periods and clotting. Adenomyosis is another condition that can cause you to experience painful periods with blood clots.

4. Perimenopause

Perimenopause often begins several years before menopause itself and commonly develops during your 40s. During this, your ovaries produce lower levels of oestrogen and progesterone consistently. These hormonal fluctuations can significantly affect how the uterine lining builds up and sheds each month, leading to heavier or irregular periods. As ovulation becomes less predictable, it also leads to a decrease in progesterone production.

D] What Signs Point Towards Abnormal Period Clots?

Abnormal menstrual clotting is often accompanied by symptoms that gradually worsen over time. Symptoms such as increasing menstrual pain, progressive heaviness, or worsening clot formation should ideally not be ignored. 

• Repeatedly passing large clots or experiencing persistent heavy bleeding 
• Menstrual bleeding that requires changing sanitary protection every one to two hours 
• Bleeding that continues beyond seven days, accompanied by clotting or bleeding
• Mild to moderate cramping during menstruation due to uterine contractions 
• Experiencing anaemia symptoms such as dizziness, fatigue, pale skin or weakness
• Menstrual clotting accompanied by spotting between periods 

E] How to Distinguish Between Normal and Abnormal Period Clots?

Recognising plays a key role in understanding if the clotting falls within a normal range. Factors such as size and frequency can provide vital insights if the clotting is abnormal. Here’s how to distinguish between the two:

1. Normal period clots:

• Are small in size 
• Occasional rather than frequent 
• More noticeable during heavier flow days 
• Have a dark red, bright red, or brown colour 

2. Abnormal Period Clots:

• Consistently large in size 
• Occur alongside heavy bleeding 
• Interfere with daily activities 
• Accompanied by severe pelvic pain
