Menstrual cups are a type of reusable feminine hygiene products. It’s a small, flexible funnel-shaped cup made of rubber or silicone that you insert into your vagina to catch and collect period fluid. Cups can hold more blood than other methods, leading many women to use them as an eco-friendly alternative to tampons. And depending on your flow, you can wear a cup for up to 12 hours. They are also considered to be safer and better for your health than tampons in regards to toxic shock syndrome (TSS).
