Many women feel worried when their period color is not red. The first thing that comes to mind is “Is something wrong with me?” or “Do I have a health issue?”

The good news is that in most of the cases the change in period blood color is completely normal, and it is because of a few factors like oxidation, blood flow. However, in some cases, unusual colours may indicate an underlying issue that requires medical attention.

Let’s take a closer look at the different period blood colours and what they may mean.

Different Period Colors and What They Mean

1. Bright red  period blood

You would notice that the blood that comes on the first day or at the beginning of your period is often bright red with heavy blood flow. Bright red period blood usually indicates fresh blood that leaves the uterus quickly and has not had much time to oxidize. This is generally considered normal.

2. Dark red period blood

Dark red period blood is slightly older blood that has remained in the uterus longer before leaving the body. As a result, it undergoes some oxidation, giving it a darker colour. This dark red period color occurs in the 2-4 days of bleeding with moderate blood flow.

3. Brown period blood

Brown period blood is usually older blood that has taken longer to leave the uterus. The longer exposure to oxygen causes the blood to turn brown. You would notice this brown blood at the end or at the beginning of your period with slower blood flow.

4. Black period blood

The black menstrual blood is the very old blood that has oxidised heavily. This occurs either in the beginning or at the end of periods, but if you feel pain, unusual odor, or some sort of discomfort, do consult healthcare professionals.

5. Pink period blood

Pink period blood often occurs when menstrual blood mixes with cervical mucus. It is commonly seen during light periods or at the beginning or end of menstruation. This often comes when the period flow is light.

But if you’re pregnant and have brown or pink blood, it is important to consult professionals.

6. Grey or Green period blood

Grey or green discharge may be associated with certain infections and should not be ignored. If you notice these colours along with itching, burning, or an unpleasant smell, seek medical advice.

7. Orange period blood

Orange period blood can occur when blood mixes with cervical mucus. However, if it is accompanied by an unusual odor, itching, or irritation, it may indicate an infection.

Why Does Period Color change?

Many women notice that their period blood color is not the same throughout the cycle. In most cases, it is completely normal. The period blood color depends on many factors.

1. Oxidation – This is one of the main reasons the period color changes. Oxidation means how long the blood is exposed to oxygen, which would lead to darker blood. The fresh blood that leaves the uterus quickly is bright red in color.

2. Flow of blood – Often, when the flow is heavy, the blood is bright red in color because it didn’t stay in the uterus for too long to get oxidised, and when the flow is lighter, the period blood color could be brown or dark red because it has time to oxidize.

3. Hormonal changes, certain health conditions can also affect the colour of the period blood.

When Should You See a Doctor?

In most cases, the change in period blood is completely normal and nothing to worry about. In most of the cases, the change of menstrual blood is due to oxidation. However, in some cases, it is important to consult a healthcare professional.

You should consult a professional if the period color is grey or green, as this indicates infection. It is also important to seek medical attention if you notice a strong or unpleasant odour, severe itching, burning, or unusual discharge.

Consider seeing a doctor if you experience:

• Severe abdominal pain during period
• An extremely heavy period that soaks your pads or tampon, really quickly.
• Period becomes irregular
• Getting periods twice a month
• Fever along with unusual vaginal discharge
• Black discharge accompanied by pain or discomfort

If you are pregnant and notice pink, brown, or any unexpected bleeding, it is important to contact your healthcare professional

While period blood can range from bright red to dark brown or black and still be normal, symptoms such as pain, fever, unusual odour, or significant changes in your menstrual cycle should not be ignored.When in doubt, you should not hesitate to consult a doctor.
