What does healthy period blood look like? Breaking the taboo around menstrual color, smell & texture

Menstruation is a vital sign of health, yet many people feel uncomfortable talking about what their period blood actually looks or smells like. This silence can lead to confusion, shame, and missed opportunities to detect health issues early. Let’s break that taboo!

What does normal period blood look like?

Menstrual blood is not just blood - it’s a mix of blood, cervical mucus, vaginal secretions, and endometrial tissue. Its appearance can vary throughout your cycle and from person to person.

Normal colors:

Bright red: Fresh blood, common at the start of menstruation.

Dark red or brown: Older blood that’s been exposed to oxygen.

Rusty or orange: May be mixed with cervical fluid. Usually harmless unless accompanied by odor or discomfort.

Pink: Often diluted with cervical fluid or linked to low estrogen levels.

When to be concerned:

Gray or greenish blood: May indicate infection such as bacterial vaginosis or trichomoniasis.

Bright red blood between periods: Could signal STIs or hormonal imbalance.

Black blood: Usually old blood, but if accompanied by pain or odor, consult a doctor.

What about texture?

Thin or watery: Normal in lighter flow days.

Thick or sticky: Common during heavier flow.

Small clots (less than a coin): Normal.

Large clots: May indicate hormonal imbalance, fibroids, or other conditions.

What does menstrual blood smell like?

Menstrual blood has a natural scent due to iron and bacteria in the vagina.

Normal smell: Slightly metallic or earthy.

Unusual odors:

- Fishy or rotten smell: May indicate bacterial vaginosis or infection.

- Sweet or foul-smelling discharge: Could be a sign of imbalance or STI.

If the smell changes suddenly or is accompanied by itching, burning, or unusual discharge, seek medical advice.

Menstrual health by the numbers

Over 70% of menstruating people experience some form of menstrual discomfort, yet many don’t seek help due to stigma

Up to 30% report passing clots during menstruation - most are harmless, but large clots should be evaluated.

Bacterial vaginosis, which can cause foul-smelling discharge, affects nearly 1 in 3 women at some point in their lives.

Common questions answered

1.     Is it normal for my period blood to change color?

Yes. Color changes are part of a healthy cycle. Only sudden or unusual changes (gray, green, black with pain) should raise concern.

2.     Should I worry about clots?

Small clots are normal. Large clots (larger than a coin) may indicate fibroids or hormonal issues.

3.     Why does my period smell different this month?

Diet, hygiene, infections, or hormonal shifts can affect odor. If it’s strong or unpleasant, consult a doctor.

4.     Can I track my menstrual blood to monitor health?

Absolutely. Apps and journals can help you notice patterns and changes. If something feels off, you’ll have data to share with your healthcare provider.
