If you have a heavy period flow at night and want to know how to prevent period leakage, try a double-pronged attack. Wear a night-friendly tampon like a CAREFREE® FLEXIA® tampon as well as your regular night time pad. Tampons can provide up to 8 hours night protection. Just make sure you put the tampon in just before you go to bed and take it out first thing in the morning. This way you’ll have leaks covered!
