The short explanation
Longer and heavier periods are a known side effect of the copper IUD, often called Copper T, especially in the first few months after it is put in. For many women this settles within three to six months. Some women continue to have heavier periods for as long as the device is in place. You do not necessarily need to remove it. A clinician may suggest treatments that reduce bleeding, and they will also check that the device is in the right position and that there is no infection. If bleeding remains a problem, other methods, such as a hormonal IUD, often make periods lighter. Removal is your choice at any time.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Heavier periods over months can lower iron levels, so a blood count check is a good idea if you feel tired or breathless.
- Bleeding between periods, pain, fever or unusual discharge after a Copper T are reasons to be checked sooner.
- Copper T insertion and removal are available free at many government hospitals and PHCs.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your bleeding is only due to the Copper T. A doctor can examine you and check the device position.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is my bleeding a usual side effect of the Copper T?
- Can you check that it is in the right position?
- What can reduce the bleeding if I keep it?
- What other contraception might give me lighter periods?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the nearest emergency department if bleeding is very heavy with fainting or breathlessness.
Get help the same day
- Get care the same day if you have severe pain, fever or a possible pregnancy with the Copper T in place.
Book an appointment soon
- See a doctor within a few days if you feel very tired or dizzy.
Raise it at a routine appointment
- Book a routine appointment if long or heavy periods continue beyond three to six months after insertion.
