What should you know about a hormonal contraceptive coil?

The coil thickens mucus at the cervix, making it harder for sperm to travel, and changes the womb lining. It can also reduce menstrual bleeding and cramps over time. Spotting or irregular bleeding is common after fitting while the body adjusts. Some people continue to have monthly bleeding, while others have very little or none. A hormonal coil does not protect against sexually transmitted infections.

A clinician checks your medical history and the position of the womb before fitting. Cramping during and shortly after insertion can occur. The device can be used for contraception and may also be considered when heavy bleeding is linked with conditions such as uterine fibroids or adenomyosis.

Arrange fitting with a trained clinician and discuss medicines, allergies, pregnancy possibility, bleeding patterns, and any previous pelvic infection. Keep the fitting and replacement date in your calendar. After insertion, learn how to feel for the threads if your clinician recommends checking them, and attend follow-up if offered.

Use condoms when infection protection is needed. If the coil is inserted at a time when pregnancy protection is not immediate, follow the clinician's advice about temporary contraception. Do not pull the threads or try to remove the device yourself.

Seek urgent medical help for severe or worsening lower-abdominal pain, fainting, heavy bleeding, fever, or feeling very unwell after fitting. Contact a clinician promptly if you cannot feel the threads, they feel much longer or shorter, the device is visible, or you think you may be pregnant. Sudden pain with a positive pregnancy test needs prompt assessment.

Ask which coil suits your bleeding and contraception goals, when protection begins, how long it can stay in place, what bleeding changes are expected, and which symptoms should trigger a review. You can also ask about alternatives such as the Hormonal IUD Device and how removal would be arranged.
