How about the amount of blood?

It seems that many pregnant women observe a small amount of blood that comes out with the normal discharge. However, many prefer to ignore it as a sign even though it is clearly different from menstruation.

On the other hand, there are cases when blood during implantation bleeding is almost the same as the amount of blood during menstruation. This makes it easy to confuse implantation bleeding with regular menstruation.

There is a suspicion of irregular bleeding instead of implantation bleeding

If the amount of blood during implantation bleeding is usually very small. It may be overlooked because it is difficult to distinguish it from the blood that comes out at the start and end of menstruation. Furthermore, the amount may vary from person to person.

It may not be easy to distinguish between implantation bleeding and menstruation just by judging from the amount of blood.

The pattern of abnormal bleeding is the most common

Young women, in particular, rarely have abnormal bleeding because of a disorder of autonomic nerve balance. This may be caused by stress or slight environmental changes. This type of bleeding is called functional uterine bleeding, and is one of the most common causes of irregular bleeding in young women.

Does it have Odor?

Implantation bleeding often has little odor because the bleeding from the endometrium is mixed with discharge. On the other hand, menstrual blood is one in which the old endometrium grown for about one month is peeled and discharged. Most menstrual blood is not fresh blood, and may have odor.

It’s better to check the menstrual blood every time you have. Then, you can see when it’s different and if it’s implantation bleeding.

Do you feel any pain?

It seems that some women feel pain in the uterine with the implantation. This is called implantation pain. Many people feel pain slightly in the lower abdomen rather than a strong pain.

No medical evidence

Implantation pain is not medically found. It is believed by experts that pregnant women don’t have any pain with implantation bleeding. There are also opinions that the pain related to ovulation and the uterine pain as an early symptom of pregnancy may be misrecognized as pain with implantation.

Does the high temperature period continue?

One of the first signs that you can observe in the very early pregnancy is the high temperature period. Usually, after entering the high temperature period around the day of ovulation, menstruation will begin in about 14 days. Then the body temperature will begin to lower. However, if the high temperature period continues, there is a high possibility of becoming pregnant.

Basal body temperature is one of the most effective ways to determine implantation bleeding, or the start of menstruation. It is recommended to measure basal body temperature not only to identify implantation bleeding, but also to accurately determine the ovulation cycle. These days, there are many apps for measuring basal body temperature. It’s has become easy to record, and check your basal body temperature.

Do you have diarrhea?

Hormonal balance changes significantly in the body due to pregnancy. This causes disturbance of the autonomic nerves. This can cause diarrhea, which prevent intestinal function, and poor temperature regulation.

However, even in the case of menstruation, there are changes in the hormone balance, so it seems that some women experience diarrhea as well. Also, if you usually have diarrhea before or during menstruation, it’s may even be more difficult to distinguish regular menstruation implantation bleeding.


We have explained how to tell the difference between implantation bleeding and menstruation based on time, period, amount, color, and symptoms. However, those are not 100% accurate.
