Blood Clots During Periods Causes

What are the Clots in a period of blood? Well, the following are some of the potential causes of blood clots during your menstrual cycle:

Hormonal Imbalance

There are two main hormones in the body responsible for thickening and shedding of the uterine lining.

Any change that causes an imbalance of the estrogen and progesterone level in the body may result in the thickening of the uterus that leads to the formation of blood clots during your period.

The changes in the level of estrogen and progesterone are brought about by failing to ovulate, ovarian cysts, and medication.

You should note that this change usually lasts for a short period of time and it is said to be normal among many women.

However, premenopausal changes can bring about long-term blood clots in your period since this is the time when the body experiences frequent changes in the level of hormones.

Sometimes, you may experience drastic weight loss or weight gain and other chronic diseases.

Enlarged Uterus

During the pregnancy period, the uterus gets enlarged in order to accommodate the growing fetus.

Sometimes you may experience complications such as miscarriages and ectopic pregnancies that cause the appearance of blood clots.

These complications usually require immediate medical attention in order to avoid fatal cases like death.

Normal blood clots in your periods after pregnancy usually last for a short period of time and you resume your normal periods.


According to doctors on WebMD, about 30% to 40% of women in America usually experience heavy vaginal bleeding that is either accompanied by blood clots or not. This type of vaginal bleeding is described as indirect clotting.

According to doctors on the mayo clinic, women with large endometrium usually experience heavy bleeding with blood clots.

This type of period that is accompanied by large blood clots is considered to be abnormal and this may require medical attention.


These are benign growths that mainly develop on the uterine wall and are marked by a condition that results in the vaginal bleeding that is accompanied by large blood clots.

According to gynaecologists on Cleveland clinic, these growths can also develop on the outer surface of the uterus.

This growth causes frequent contraction of the uterine wall and this may trigger the appearance of blood clots during vaginal bleeding.

It is recommended to visit your health care provider so that these growths can be removed surgically.

Outflow Obstruction

This is a condition that brings about the blockage of the blood from the uterus from coming out.

The obstruction usually results in the formation of blood clots. The obstruction could be due to the ovarian cyst and this may require medical attention.

Birth Control

There are some women whose bodies are very sensitive to the use of hormonal birth controls such as pills or non-hormonal birth control such as copper IUDs.

Some of these birth controls can cause blood disorder menorrhagia or heavy bleeding.

Other symptoms associated with the use of birth controls are longer periods than expected and heavy vaginal bleeding that is accompanied by blood clots.

It is recommended to consult your gynaecologist about the best control measure that can work for you in order to avoid the abnormal flow of blood during your periods. Excessive loss of blood during your menstrual can cause anaemia.

Clotting Abnormalities

There are some diseases such as von Willebrand that according to doctors on WebMD is said to be inherited or run through the families. These diseases usually result in abnormal bleeding during your period.

People with this type of the disease are easily bruised and they can also experience prolonged nose bleeding or gum bleeding.

It is recommended to consult your doctor for measures on how to relieve the symptoms.


This is a condition that usually occurs due to an abnormality of the uterine wall to contract. This condition usually results in the formation of blood clots in your periods.

This happens due to the enlargement of the uterus than it was before the pregnancy.

This causes pooling of blood together during the menstrual cycle and this is the time you will notice the occurrence of blood clots in the period. You should visit your doctor in case of such a condition.


These are growths inside your uterus that causes obstruction of the outflow of the menstrual blood thereby increasing blood clots during the period.

Sometimes these growths can bleed on their own. Consult your gynaecologist on how to remove these growths in the uterus.

Is It Normal To Have A Blood Clot When On Your Period?

Having blood clots in your period is a normal thing among many women. This is because blood during period changes from one type to another.

You are likely to experience large blood clots in your period once in a lifetime and this is usually not the trend in all women. This is usually depending on the type of diet and lifestyle a person has.

Blood during the period is usually bright red in colour but sometimes women may experience dense and thick red blood.

You should visit your doctor in case you have regular blood clots during your period.

Blood Clots during Period Miscarriage

Sometimes you can experience blood clots even without having periods.

What does it look like when you miscarry early? Well, the failure of an embryo to attach itself to the uterine wall may cause the growing baby to come out.

You will notice a large mass of blood clots that can be confused to an abnormally heavy period.

However, a miscarriage may not only look like blood clots but also fleshy pieces of meat.

According to doctors on WebMD, about 20 to 30% of pregnancies may end up in miscarriage before the growing baby reaches the 20th week in the United States of America.

This is because most women may not know if they are pregnant so when they miscarry they confuse it with heavy vaginal bleeding.

What do big blood clots in period mean? Well, large blood clots are the common symptom of a miscarriage apart from abdominal pain.

You should also note that having a heavy downfall in the vagina is not an indication of a miscarriage.

Large Blood Clots during Period

Are large blood clots normal during the period? Yes. Having large blood clots that look like jelly-like blood clots during the period is normal and it is usually dark red in colour. Most women usually notice these blood clots on the pad or tampons.

This is just normal blood that turned into masses may be due to various reasons. Some reasons may be mild while others so serious such that they may require medical attention.

Having large blood clots during your periods is considered to be normal for many women and it may due to serious conditions that are not life-threatening.

Some women may get scared since these large blood clots look like an internal organ coming out of your body but they are just large lumps of blood.

This happens because a woman’s body may release anticoagulants during monthly periods, which may break down the uterine tissue and prevent blood clots in it.

However, when the period is typically heavy, the blood flow may be sometimes too fast so that the anticoagulants can function effectively thus leading to blood clots.

According to doctors on WebMD, blood clots during the period that is smaller than a quarter are normal and should not raise concern.

You should visit your doctor in case you have blood clots associated with the heavy flow each month.

Sometimes the period is accompanied by cramping- a pain that is felt like squeezing of the stomach. Women who have gone through this can explain this better.

If your pain is so severe, it is advisable to consult your doctor for examination and diagnosis. This could be an indication of a serious medical condition.

Blood Clots during Period Bigger Than a Quarter

The amount and type of blood clots in every woman’s menstrual blood vary from each and every woman, and in other cases, the clots may be larger that quarter.

Normally, blood clots in period should be an on and off condition and if it happens it comes every month especially with larger clots, this could be a medical concern.

Usually, the presence of large clots with a heavy flow of blood is an indication of a problem.

Any condition in the body that causes an increase in blood flow can cause period larger that quarter.

This condition is relevant mostly when blood pools in the uterus or its flow are obstructed in the uterus as we said above, giving the blood enough time to form large clots.
