What should you know about a non-copper coil?

A non-copper coil is usually a hormonal intrauterine device that releases progestogen in the womb to prevent pregnancy. It is placed inside the uterus by a trained healthcare professional. The hormone mainly thickens cervical mucus, making it harder for sperm to pass, and also changes the lining of the womb. It does not contain copper.

People commonly use “non-copper coil” to mean a hormonal coil. It is a long-acting form of contraception that works without needing daily action, although it does not protect against sexually transmitted infections. Periods may become lighter, shorter, or less predictable after insertion; some people stop bleeding, while others have spotting during the adjustment period. Cramping during or shortly after insertion can happen. A clinician will consider your medical history, bleeding pattern, medicines, and pregnancy possibility before recommending it.

Before fitting, tell the clinician about unexplained bleeding, pelvic infection, recent unprotected sex, previous ectopic pregnancy, and any medicines or allergies. Ask how pregnancy will be excluded and when the device becomes effective, because timing can affect whether additional contraception is needed. After fitting, follow the clinic’s advice about checking the threads and arrange any recommended follow-up. Keep a note of your bleeding pattern and pain so changes are easier to describe. If the device is expelled or you cannot feel the threads as expected, use backup contraception and contact the clinic.

Get urgent medical advice for severe or worsening lower-abdominal pain, fainting, heavy bleeding, fever, or unusual-smelling discharge after insertion. Seek prompt care if you think you may be pregnant while the coil is in place, particularly if you have one-sided pain or shoulder-tip pain. These symptoms can have several causes, but they need assessment because infection, expulsion, or pregnancy outside the womb may require treatment. Contact a clinician if pain during sex continues, bleeding remains troublesome, or the threads feel different.

Useful questions include: Is a hormonal coil suitable with my health history? How will insertion be managed if I am worried about pain? When will contraception start working for me? Which bleeding changes should I expect? How should I check the threads, and who should I contact if they change? What should I do if I want the coil removed or want to become pregnant?
