Your period is more than just a monthly routine — it’s one of your body’s ways of keeping you informed about your overall health.
One of the easiest things to notice? The color of your period blood. It can change throughout your cycle, and each shade might tell you something different. Let’s explore what those colors could mean — and when it might be a good idea to check in with your doctor.

1. Bright Red Blood

What it could mean:
Fresh blood and a steady flow.

When you might notice it:
Usually appears during the early days of your period.

Bright red blood means that your uterine lining is shedding as expected. It’s fresh, active bleeding — and usually a sign that everything is working just fine.
If, however, you notice bright red spotting outside your usual cycle, it’s worth bringing up with your doctor.

2. Dark Red or Brown Blood

What it could mean:
Old blood that’s taken a bit longer to exit the body.

When you might notice it:
Usually appears during the early or final days of your period.

As blood stays in the uterus longer, it oxidizes and turns darker — often deep red or brown. This is very common and nothing to be alarmed about.
Your body is simply finishing up the shedding process.

3. Pink Blood

What it could mean:
Lighter bleeding mixed with cervical fluid.

When you might notice it:
Common around the start or finish of your period, and sometimes during ovulation.

Pink blood usually means the flow is light and slightly diluted. It can be caused by hormonal changes, heavy workouts, or lower estrogen levels.
If it shows up occasionally, it’s fine — but if it’s frequent or consistent, check with your healthcare provider.

4. Orange Blood

What it could mean:
May indicate a mix of blood and cervical fluid, or in some cases, point to an infection.

When you might notice it:
Rarely — during light spotting or unusual bleeding.

Orange blood is less common. While it might simply be a result of mixing with cervical fluid, if it’s accompanied by itching, discomfort, or an unusual smell, it could signal an infection.
It’s better to get it checked out early.

5. Gray Blood

What it could mean:
Could suggest an infection, or if you’re pregnant, may be a warning sign of miscarriage.

When you might notice it:
Rarely — but if it happens, see your doctor immediately.

Gray blood is not normal and should never be ignored. If you’re not pregnant, it could indicate a bacterial infection like bacterial vaginosis. If you are pregnant, it might be a sign of miscarriage and should be addressed right away.

When Should You See a Doctor?

• If your period blood has a strong, unpleasant smell.

• If you regularly notice gray or orange blood.

• If your bleeding is extremely heavy or very painful.

• If you notice unexpected spotting between your periods without a clear cause.

• If anything about your cycle feels unusual or off.

Every period is a little different — and that’s completely normal. But learning to recognize the signals your body is sending can help you stay informed and healthy.
Most color changes are harmless, but if something doesn’t feel right, trust your instincts and talk to a medical professional.
Your body speaks to you — all you need to do is listen.
