Is it safe to use the Mooncup with an IUD or IUS (coil)?
We know that there are Mooncup® users who are happily using their Mooncup alongside an IUD/IUS (coil), however there have been some instances where an IUD/IUS has become dislodged when using the devices together. This may be due to anatomical factors (e.g. a low cervix), usage issues (e.g. wearing the Mooncup too high) or simply that the IUD/IUS has been naturally rejected by the body. One in twenty IUD/IUS will be expelled, most commonly, in the first 3 months after the device has been inserted. These expulsions happen most frequently during menstruation.
If you are using the Mooncup menstrual cup alongside an IUD/IUS, check you can still feel the IUD/IUS strings after each period. If you cannot feel them or think that your IUD/IUS has moved or is causing/has caused you pain, use another form of contraception such as a condom until you have had your IUD/IUS checked by a doctor or medical professional.
If you are thinking about using the Mooncup menstrual cup alongside an IUD/IUS, consult your doctor, IUD/ IUS fitter, or gynaecologist first. If you would like to take a Mooncup® usage guide to your consultation please contact us.
Please also consider the following information:
- There should always be a space between the Mooncup and the cervix. If you have a low sitting cervix there may not be enough room for the Mooncup to sit safely and work effectively alongside your IUD/IUS.
- The Mooncup is designed to be worn as low as it will comfortably sit in the vagina and form a light seal with the walls of the vagina (read more about Mooncup positioning).
- It is important to release the seal before removing the Mooncup.
