In a healthy period, you should bleed from 3 to 7 days and lose between 25 and 80 ml of blood. Knowing how much you bleed can tell you if there is a hormonal imbalance:
- Bleeding less than 25 ml or less than three days may indicate that your reproductive hormones are too low.
- On the other hand, menstrual bleeds of more than 80 ml or more than seven days are known as menorrhagia, which can eventually lead to anemia. Heavy periods are associated with high estrogen levels, endometriosis, thyroid disorders, uterine fibroids, and other conditions.
To objectively measure how much you bleed, keep track of the size or volume of the menstrual product you use, how often you change it during the day, and how full it is when you change it.
Here’s a guide to how much each menstrual product absorbs:
For pads and tampons:
- Light flow – up to 3ml.
- Medium flow – up to 5 ml.
- Heavy flow – up to 8ml.
- Super pads and tampons – up to 12 ml.
- The menstrual cup has an average capacity of 30ml. Every brand is different, so check yours.
At the end of your period, add up your records, and voilà!
Of course, your estimation doesn’t have to be precise (it would be impossible!), But this will give you a close idea. If your menstrual product isn’t full to its max capacity, make an estimate. For instance, if I notice that only 1/3 of my cup was full, I’ll record 10 ml, etc.
