The coil threads are attached to the end of the coil. They can be felt with your fingers at the centre of the cervix, which is at the top of the vagina. We ask women to check their threads initially every four weeks after fitting to ensure the coil has not moved out of place, especially after a period. This can then be extended to every few months. If you cannot feel the threads or are not unsure about what you are feel, contact us at the clinic.
