If you are going to be running out and
about on a hot day I would prefer to use a
menstrual cup or
more breathable cloth pad option.
And while
menstrual cups are safe to keep in for up to 12 hours, Dr. Berens is skeptical that they'll last that long, especially for those with super heavy flow: «I'd recommend changing them
more frequently —
about as often as you'd change an extra-large tampon — to avoid accidents,» she says.
