Sleeping with menstrual cup are they painful?

"Many patients are asking questions whether it is safe to use a menstrual cup while sleeping. It is a device that is made of a flexible material. Once placed in, there is no place where it will be lost. It just collects the blood and the only thing you will feel is overnight if there is a bleeding which is collected in the menstrual cup, then you can use an additional pad . Otherwise it is very safe to keep the menstrual cup overnight. First anything which we learn new or we start using as a new attempt, you may find difficulty in using a new thing, and you may find it a bit painful also. But with your own method of pressing the menstrual cup, usually the process is pain free. As I told, everything has a learning curve. There is no correct or wrong method to use a menstrual cup. You just have to compress it into a cone or a C shaped and keep it and it takes its full form and usually it is not painful. Usually these are big enough and there are different sizes available depending on the need of the patient and ofcourse if it is full, it will leak, it is obvious. So usually a patient will understand their need after using it for a while and usually a menstrual cup can be kept for 6 to 12 hours. You can change a cup after 6 to 12 hours and if you feel that you are afraid that it will leak, you can keep an extra pad during the night time"
