Facts & Figures
The average menstruation lasts for 5 days. However, there are also women who only have their period for 2-3 days a month. And if you’re unlucky, the bleeding can continue for 7 days or even longer.
The word menstruation derives from the word mensis, Latin for month. A lunar month is meant here, not a calendar one.
