What should you know about mini copper coil?

The device is placed inside the womb by a trained clinician. Copper changes the local environment so sperm movement and fertilisation are disrupted. It does not contain contraceptive hormones and can provide contraception without requiring a daily tablet. The word mini usually describes a smaller device or a particular product; the exact size, duration of use, and suitability depend on the device available and your anatomy.

Periods may become heavier, longer, or more crampy after fitting, especially at first. Some people have spotting or cramps for a short time. A copper coil does not protect against sexually transmitted infections, so condoms may still be useful depending on your circumstances.

Ask a clinician which copper device is available, how long it is intended to remain in place, and whether it suits your health history. Before fitting, mention possible pregnancy, unexplained bleeding, pelvic infection, allergies to copper, and any medicines or procedures that affect bleeding.

After fitting, follow the instructions about checking the threads if you have been advised to do so. Use the recommended pain relief if you can take it. Arrange review if pain or bleeding does not settle, or if you cannot feel the threads or feel the hard device at the cervix. A clinician can remove the coil when you want to try for pregnancy or change contraception.

Seek urgent medical help for severe or worsening lower-abdominal pain, fainting, fever, vomiting, or heavy bleeding after fitting. Prompt assessment is also needed if you have a positive pregnancy test with a coil in place, new pain during sex, or unusual-smelling discharge. These symptoms can have several causes, including infection, expulsion, or pregnancy outside the womb, and need clinical assessment rather than self-diagnosis.

Which copper coil size and duration fit my needs? What bleeding changes should I expect? When can I return to exercise or sex? How should I check the threads, and what should I do if they change?
