Implantation Bleeding: An Overview

Have you ever experienced unexpected spotting between your periods? If so, you're not alone! Many women experience this phenomenon, which can be confusing and even worrying. But don't fret! This spotting could be implantation bleeding, an early sign of pregnancy.

Let's unravel the science behind implantation bleeding, decipher how it differs from your regular period, and uncover its importance.

Let's dive in!

What Is Implantation Bleeding?

Implantation bleeding is a light spotting or bleeding that occurs when a fertilised egg attaches to the uterine lining.¹ It is often mistaken for a period but is actually a sign of early pregnancy.¹

Let’s take a look at the causes of implantation bleeding.

Causes Of Implantation Bleeding

The most common cause of implantation bleeding is disruption of blood vessels in the uterus lining. When a fertilised egg embeds itself into the uterine lining, it breaks tiny blood vessels, resulting in slight spotting or light bleeding. ²

However, here are some other reasons why you might bleed during pregnancy:

• Miscarriage is when the pregnancy ends before 20 weeks. Miscarriage is common, affecting about 10 to 15% of pregnancies. It can cause heavy bleeding, cramping, and pain.^{7 8}
• Ectopic pregnancy is when the pregnancy implants outside of the uterus, usually in the fallopian tubes. Ectopic pregnancies can cause heavy bleeding, pain, and nausea.^{7 9}
• Placenta previa is when the placenta implants in the lower part of the uterus, partially or entirely covering the cervix. Placenta previa can cause bleeding during pregnancy, especially in the third trimester.^{9 10}
  Infections such as UTI or STIs like Chlamydia and Gonorrhoea can sometimes cause bleeding during pregnancy.⁷ 

When Does Implantation Bleeding Occur?

Implantation bleeding typically occurs 6 to 10 days after conception. This subtle sign often appears around the time you expect your period.^{1 2 3}

Now that you know about implantation bleeding, let's explore other early signs.

Now, let’s understand the key differences between implantation bleeding and a normal period.

If you are unsure what you are experiencing, it is best to see your doctor.

Now that you know how implantation bleeding differs from a regular period, let's explore the treatment options.

Implantation Bleeding Treatment

No specific treatment is required for implantation bleeding, as it naturally resolves in a healthy pregnancy. Usually, using a panty liner is sufficient for managing light bleeding. If the bleeding soaks through a pad, it's probably not implantation bleeding, and it's better you consult a doctor as soon as possible.²

If you experience heavy bleeding, cramping, or other concerning symptoms during pregnancy, it's important to see your doctor right away to rule out any serious underlying causes.

In light spotting resembling a period, such as implantation bleeding, take a moment to relax and embrace the early stages of your pregnancy.
