What happens if the threads from a Mirena coil are too short?

If the threads from a Mirena coil are too short, it may be difficult for a healthcare provider to retrieve the device when necessary. Short threads can also lead to concerns about the IUD being properly positioned or potentially becoming dislodged. If the threads are too short, it's important to consult with a healthcare professional for an evaluation and possible imaging to assess the situation. In some cases, the IUD may need to be removed or replaced.
