If you’re comfortable with a slim tampon for four hours, chances are you have a light flow. If you need to change your tampon between Friends and Leno, you probably have medium flow.

Even at your heaviest, the most you’ll probably need is a super. If you’re running through a super every other hour, graduate to a super plus and use a pad for backup. But that’s a pretty heavy flow, so you should let your doctor know.
