Implantation bleeding is light bleeding caused by a fertilized egg implanting itself into your uterine line. This happens between 6 and 12 days after fertilization.
Your uterine lining may burst during implantation. This can release blood.
Although it is easy to mistake implantation bleeding for your period’s start, other symptoms can accompany it, including:
- Backaches, particularly in the lower back
- Breast tenderness
- Headaches
- Mild cramping
- Mild nausea
It can be so heavy!
Implantation bleeding is typically very light and lasts only a few days. Although it might be sufficient to warrant wearing a panetyliner, it is not enough to soak a tampon.
In rare cases, however, implantation can be more difficult. This is usually the case for those with an underlying bleeding disorder that impairs blood’s ability to clot.
Is it possible to be red?
Implantation bleeding is generally lighter than menstrual blood which is often dark red.
In general, implantation bleeding can be a range of colors from a light pink color to a rusty-like color.
It can cause clots.
Clots are not usually caused by implantation bleeding. Clots are usually the result of heavy menstrual flow.
It could be anything else.
It is possible to have implantation bleeding if your menstrual cycle is not followed. This is especially true when the bleeding is severe.
Another possible cause of unusually heavy bleeding is:
- Bleeding disorders. Hemophilia, von Willebrand disorder, and other conditions can lead to excessive or uncontrolled bleeding.
- Cervical infection. These infections can be caused by a sexually transmitted disease, such as chlamydia and gonorrhea.
- Ectopic pregnancy. This is when the fertilized egg implants outside the uterus, most often in the fallopian tube. This is a medical emergency that requires immediate attention.
- Birth control. An infection can cause bleeding from an intrauterine device or hormonal changes due to birthcontrol pills.
- Uterine cancer. Uterine cancer is a rare cause of uterine bleeding. Symptoms can be similar to implantation bleeding.
- Uterine fibroids. These benign uterine growths may cause bleeding.
- Uterine Polyps. Hormonal changes can cause uterine polyps and uterine cell overgrowth.
When should you see a doctor?
You should always consult your healthcare provider if you notice unusual uterine bleeding.
You may be experiencing implantation bleeding if you are already pregnant.
The American College of Obstetricians and Gynologists estimates that 15 to 25% of women experience bleeding during their first trimester. The cervix creates blood vessels that support the growing uterus of a woman during pregnancy.
However, your healthcare provider is the best way to determine the cause of your bleeding. They’ll likely begin with blood tests and an ultrasound, depending on your medical history and other symptoms.
The bottom line
Implantation bleeding is one of the early signs of pregnancy. Implantation bleeding is not usually severe unless there are other bleeding disorders.
Your healthcare provider should be consulted if you experience excessive bleeding that is not related to your menstrual cycle. They will be able to diagnose the problem and offer treatment options.
