How big are miscarriage clots?

Miscarriage is a distressing and often heartbreaking experience for many women. It refers to the loss of a pregnancy before the 20th week, and it can be accompanied by various symptoms including heavy bleeding and the passing of clots. Understanding the size of miscarriage clots is important for women going through this difficult time, as it can provide insight into what to expect and when to seek medical help. In this article, we will explore the different sizes of miscarriage clots, factors that can influence their size, physical and emotional experiences associated with them, medical guidance and support, as well as possible complications and risks.

Characteristics of Miscarriage Clots

When experiencing a miscarriage, women may pass clots of different sizes. These clots can range from small to medium-sized, and in some cases, even large.

1. Small Clots

Small clots are commonly seen during a miscarriage. They can vary in size, but are typically compared to the size of a 50p piece. These smaller clots may be passed along with heavy bleeding. It’s important to note that the size of the clot does not necessarily correlate with the severity of the miscarriage.

2. Medium-sized Clots

Medium-sized clots are larger than small clots and are often likened to the size of a golf ball. These clots may also be accompanied by heavy bleeding and may cause discomfort or pressure during passage.

3. Large Clots

In some cases, women may pass larger clots during a miscarriage. These clots can be as big as a tennis ball. Passing larger clots may be more physically intense and painful than passing smaller ones. It’s important to keep in mind that individual experiences can vary, and not all women will experience large clots during a miscarriage.

The frequency and amount of clots can also vary from woman to woman. Some may pass a few clots, while others may pass multiple clots over a longer period of time. It is important to remember that each miscarriage experience is unique and that clot size and quantity can vary.

Factors Influencing Clot Size

Several factors can influence the size of miscarriage clots. The gestational age at which the miscarriage occurs is one such factor.

A. Gestational Age

Early miscarriages, which occur in the first trimester, may involve smaller clots compared to late miscarriages, which occur after the first trimester. This is because the size of the gestational sac and the fetus is smaller in early pregnancy, resulting in smaller clots during a miscarriage. Late miscarriages, on the other hand, may involve larger clots due to the more developed state of the pregnancy.

B. Cause of Miscarriage

The cause of a miscarriage can also impact the size of the clots. Genetic abnormalities in the embryo or fetus can lead to a miscarriage, and these abnormalities may influence the size of the clots. Hormonal imbalances can also play a role in miscarriages, potentially affecting the size of the clots.

Physical and Emotional Experiences with Clots

During a miscarriage, women may experience various physical symptoms associated with passing clots.

A. Physical Symptoms

1. Pain during clot passage: Passing clots can be accompanied by cramping or sharp pains in the lower abdomen.
2. Discomfort or pressure: Women may feel discomfort or pressure during the passage of clots.
3. Duration of clot passage: The length of time it takes to pass the clots can vary. Some women may pass them quickly, while for others, it may take longer.

B. Emotional Impact

Experiencing a miscarriage can have a significant emotional impact. It is common for women to feel sadness, grief, and a range of other complex emotions. Coping mechanisms and support from loved ones or support groups can play a crucial role in navigating this emotional journey.

Medical Guidance and Support

Seeking medical guidance and support is vital during a miscarriage.

A. Seeking Medical Advice

Knowing when to contact a healthcare provider is important. If you experience heavy bleeding along with large clots, severe pain, or prolonged bleeding, it is recommended to seek medical advice immediately. A healthcare professional can provide an accurate diagnosis and offer appropriate guidance and support.

B. Managing Heavy Bleeding and Clots

Managing heavy bleeding and clots is an essential part of the miscarriage process. Healthcare providers may recommend specific approaches such as rest, hydration, and the use of pain medication. Additionally, the use of sanitary products like pads may be advised to manage bleeding and the passage of clots.

Possible Complications and Risks

While miscarriages are common, there are potential complications and risks that women should be aware of.

A. Excessive Bleeding

Excessive bleeding during a miscarriage can be a cause for concern. If bleeding becomes uncontrollable or if you experience symptoms such as dizziness or lightheadedness, it is important to seek emergency care immediately. Medical interventions, such as medication or procedures, may be necessary to control the bleeding and ensure your safety.

B. Incomplete Miscarriage

An incomplete miscarriage occurs when not all of the pregnancy tissue is passed from the uterus. This can lead to ongoing symptoms such as continued bleeding or infection. If you suspect you may be experiencing an incomplete miscarriage, it is crucial to seek medical evaluation. Treatment options may include medication to help complete the miscarriage or a surgical procedure called a dilation and curettage (D&C).


Understanding the size of miscarriage clots can provide important insight into what to expect during a miscarriage. Small, medium, and large clots can be passed during this difficult time. Various factors, such as gestational age and the cause of miscarriage, can influence the size of the clots. It is important to seek medical guidance and support, as well as to address the emotional impact of a miscarriage. Remember, each woman’s experience is unique, and finding adequate support can aid in the healing process.
