I have been using menstrual cup more than 1 year. I have been using Sirona menstrual cup before. It was super comfortable for me. But due to color change as well as some kind of texture change in the sirona cup made me to by another menstrual cup. So i choosed femisafe. This one is not at all comfortable. And also not flexible. I feel pain while inserting as well as taking off. And also i feel pain whenever i move like sit, stand etc… the tip of the stem of the cup is little bit longer than usual .. so it is not going inside and it is touching the private area part making it more painful. And also feeling like air is trapped inside causing more pain in the abdomen area other than the period pain.
