When will I know I need to replace my menstrual cup?
Even though the shelf-life of a certain menstrual cup has an average time when the manufacturer recommends it be replaced, you can gage when you need to purchase a replacement by considering how worn it is, stained, and considering when you first purchased it. If your cup shows signs of becoming damaged by your next period, it is suggested you order a new one so it is shipped and received in time for you to conveniently use it your next period.
