How much does a woman bleed on her period per day?
On average, a woman loses about 30 to 40 milliliters (ml) of blood during her entire menstrual period, which usually lasts between 3 to 7 days. This is roughly 2 to 3 tablespoons in total.
Typical Daily Bleeding Amount
| Day of Period | Average Blood Loss | Notes |
|---|---|---|
| Days 1-2 | 10-15 ml per day | Heaviest bleeding usually occurs here |
| Days 3-5 | 5-10 ml per day | Flow starts to lighten |
| Days 6-7 | Less than 5 ml per day | Spotting or very light bleeding |
What’s Considered Normal?

Losing less than 80 ml per period is generally normal.
-
Heavy bleeding (menorrhagia) is when you lose more than 80 ml or need to change pads/tampons every 1-2 hours.
-
Light bleeding or spotting can also be normal for some women.
