English: Menstrual cup use. (a) Users find a fold suitable for them; punchdown-fold, 7-fold, and c-fold illustrated. (b) The folded menstrual cup is inserted and allowed to spring open. (c) To ensure the menstrual cup is fully open and therefore creating a seal against the vaginal wall, users can run a finger around the vessel to feel for bumps as a sign it is not open, or users can gently pinch and twist the menstrual cup. (d) The menstrual cup sits lower than a tampon. The stem may need to be trimmed to avoid discomfort. The length of the vaginal canal will affect where the menstrual cup sits in relation to the cervix. (e) To remove, users must ensure the seal is broken by running a finger cup the side of the menstrual cup, or pinching the base of the vessel. The cup is then gently removed, and it can help shift the menstrual cup from side to side. (CC-BY 4.0 text from (January 2021).
