The frequency of changing menstrual products depends on the type of product used and the heaviness of your flow. Generally, tampons should be changed every 4-6 hours, sanitary pads every 4-6 hours, and menstrual cups should be emptied every 8-12 hours. However, during the heavier days of your period, you may need to change them more frequently. Always follow the manufacturer's guidelines and your comfort level.
