If you’re trying to conceive or wondering whether you're pregnant, you may have heard of implantation bleeding. But what exactly is it, and how do you tell the difference between implantation bleeding and a regular period?

In this article, we’ll break down what implantation bleeding is, when it occurs, what it looks like, and how to tell it apart from your menstrual cycle.

What Is Implantation Bleeding?

Implantation bleeding is light spotting or bleeding that can occur when a fertilized egg attaches to the lining of your uterus. This is one of the earliest signs of pregnancy, though not all women experience it. It typically occurs about 6 to 12 days after ovulation, or around the time your period would normally start.

When Does Implantation Bleeding Happen?

Implantation bleeding usually happens between 10 to 14 days after conception, which often overlaps with the expected start of your period. Because of this timing, many people confuse implantation bleeding with a light menstrual period or spotting before a period.

What Does Implantation Bleeding Look Like?

Implantation bleeding is often described as:

Light pink or brown in color
Very light flow (not enough to fill a pad or tampon)
Short-lived, typically lasting a few hours to a couple of days
Not accompanied by clots

In contrast, a normal period typically involves:

Red blood
Heavier flow
Lasts 4–7 days
Includes blood clots and cramping

Other Symptoms That May Accompany Implantation Bleeding

In addition to spotting, some people may notice other early signs of pregnancy, including:

Mild cramping
Breast tenderness
Nausea
Fatigue
Lightheadedness

If you notice these symptoms along with light spotting, it may be time to take a home pregnancy test or consult your healthcare provider.

When Should You Take a Pregnancy Test?

If you suspect implantation bleeding, wait a few days before taking a pregnancy test. Most home pregnancy tests are most accurate after a missed period, but some may detect pregnancy as early as 10 days after ovulation.

When to See a provider

While implantation bleeding is usually harmless, you should contact a healthcare provider if:

Bleeding is heavy or accompanied by severe pain
Spotting lasts longer than a few days
You have a history of miscarriage or ectopic pregnancy

Final Thoughts

Implantation bleeding is a normal and often early sign of pregnancy, but it can easily be mistaken for a light period. Paying attention to the timing, color, flow, and symptoms can help you tell the difference. If you’re unsure, a pregnancy test and a visit to your midwife can give you clarity.
