Q: How long can I wear a tampon?
A: When using tampons, it's important to choose the lowest absorbency necessary for your menstrual flow. And because the amount of flow varies from day to day, it's likely that you will need to use different absorbencies on different days of your period. Selecting the right absorbency comes with experience, but as a guide, if a tampon absorbs as much as it can and has to be changed before 4 hours, then you may want to try a higher absorbency. On the other hand, if you remove a tampon and after 4-8 hours white fiber is still showing, you should choose a lower absorbency.
