Periods, by nature, can vary — from person to person and even from month to month. So if you’re wondering why your period is lighter than usual this month, you certainly won’t be the first person to have questioned it. In the same way that the length of time you bleed for or day of the month you get your period can change, it’s also common for the amount of period blood you lose to differ.
Sometimes, a light flow can just be part of the regular fluctuations of your period, and often a period will start light before becoming heavier. But occasionally, it can also be a signal that there’s something else going on. Here, three experts break down why, exactly, your monthly bleeding may be light and also explain how to know when it’s time to see a medical professional.
