Period: What the color, amount, and consistency of your menstrual blood reveal about your health.

Period Blood

Your period is a natural, healthy part of your cycle – and yet it's still surrounded by uncertainty, unanswered questions and stubborn myths. Here you'll find clear, reliable information about menstruation: what's normal, what isn't, and what your period can tell you about your overall cycle health.

What Actually Happens During Your Period?

Menstruation is the shedding of the uterine lining that built up during the second half of your cycle. It marks day one of a new cycle. The average period lasts between 3 and 7 days, with a blood volume of roughly 1 to 3 oz (30 to 80 ml) – though both vary significantly from person to person.

What Does Your Period Blood Tell You?

The color, amount and consistency of your menstrual blood can offer important clues about your cycle health. Bright red, flowing blood is generally considered a sign of a healthy period. Dark, clotty blood can indicate sluggish flow, while very light or sparse bleeding may have hormonal causes. In the period blood section on the Daysy website you'll find a detailed guide to help you interpret what you're seeing.

Spotting vs. Period – What's the Difference?

Not every bleed is a full period. Spotting can occur just before or after your period, or around ovulation. It differs from menstruation in amount, duration and consistency. Daysy and the DaysyDay App help you identify patterns over time and understand what your body is communicating.

Why Is My Period Late?

A late period can have many causes – stress, travel, changes in weight, lack of sleep or hormonal fluctuations. Because Daysy tracks your basal body temperature every morning, it can tell you whether and when ovulation actually occurred – giving you valuable context for understanding why your period may be delayed.

Common Period Myths – Debunked

Menstrual syncing with other women is not scientifically supported – it's a popular myth. Exercising during your period is healthy, not something to avoid. And no, your period does not detox or cleanse your body in any medical sense. This section is built on facts, not folklore.
