How often should I replace my menstrual cup to ensure optimal hygiene and functionality? Is there a definitive timeframe or specific indicators that signal the need for a replacement? Considering the longevity of such a product, what factors should I account for? Could the material, such as medical-grade silicone or rubber, dictate a different replacement schedule? Moreover, does the frequency of usage or personal health conditions influence how long a menstrual cup can effectively remain in service? While some practitioners might suggest a general guideline—say every one to five years—how do I recognize signs of wear and tear? Are there particular visual cues or changes in scent that might alert me to impending obsolescence? How can I ascertain that I’m maintaining the right balance between sustainability and health by not overusing a menstrual cup that might have reached its limits? In navigating these complexities, what insights can aid my decision-making?
