What should you know about copper helical coil?

The device is placed in the uterus by a trained healthcare professional. Copper changes the local environment so sperm movement and function are disrupted, making fertilisation less likely. It does not contain contraceptive hormones, so it does not work by suppressing ovulation.

Periods may become heavier, longer, or more crampy after insertion, especially during the early adjustment period. Some people notice spotting or cramps. The coil does not protect against sexually transmitted infections, so condoms may still be useful when infection protection is needed.

Before insertion, tell the clinician about heavy periods, severe menstrual pain, recent pelvic infection, unusual bleeding, possible pregnancy, allergies, and any medicines that affect bleeding. They can discuss whether a copper coil suits your medical history and contraception goals.

After insertion, follow the personalised advice you were given. Mild cramping and light bleeding can occur. Ask how to check the strings if you want to monitor that the device remains in place, and arrange review if the strings feel different or cannot be felt.

Contact a healthcare professional promptly for severe or worsening pelvic pain, fever, foul-smelling discharge, very heavy bleeding, pain during sex, or concern that the coil has moved or come out. Seek urgent assessment if you might be pregnant and have strong abdominal pain, dizziness, fainting, or unusual bleeding.

A missed period with pain should be checked rather than ignored. A clinician can assess the coil position and investigate infection, pregnancy, or another cause of symptoms.

Ask how insertion may feel, what pain relief is appropriate for you, how long cramping or spotting may last, when to arrange a check-up, and what to do if the strings change. You can also ask whether a copper option or a hormone-releasing option better fits your periods and contraception preferences.
