It is possible for the Mirena Coil (or Mirena IUD) to fall out or become dislodged, but if this is going to happen, it’s usually within a week of it being fitted. This is called expulsion. 

Whenever a medical procedure takes place, there’s always a risk that your body won’t react as expected. And it’s exactly the same when it comes to birth control. Whether you’re on the pill and you have breakouts, you’re on the implant and have mood swings, there’s always risks. 

What is the Mirena Coil?

The mirena coil (or IUD if you’re in the States!) is a form of long-term contraception. It is T-shaped, made of a soft plastic and is fitted directly into the uterus by a healthcare provider. Two strings come out of your uterus which are attached to the coil – these will help you know it’s in place and help with removal. 

Unlike the copper coil, the mirena coil releases the hormone progesterone to prevent ovulation and thicken the cervical mucus, making it harder for the sperm to reach the egg.

The Mirena Coil Falling Out

It is possible for the mirena coil to fall out or be expelled, but if it’s going to happen, it’s likely to be around your period. It’s also possible for your coil to be partially expelled, so you might feel some of the plastic coming out of your uterus. 

If your coil partially falls out, seek medical advice immediately. Don’t try to put it back yourself, as you could cause serious complications like perforating the uterus. If the coil does partially fall out, you will have to have it taken out. 

Remember, if your coil does partially or completely fall out, it’s likely that you’ll know about it. If you’re anything like me, that thing hurt going in, so it’s likely to hurt on the way out too! If your coil is completely or partially expelled, you may experience:

  • Painful cramping
  • Heavy bleeding
  • Abnormal discharge
  • Fever (possible sign of infection)

Additionally, if you fit any of the below, your coil is more likely to be fully or partially expelled:

  • Never been pregnant
  • Have heavy, painful periods
  • Younger than 20
  • The IUD is inserted after an abortion, during the second trimester

Checking Your Mirena Coil

You should check your mirena coil after every period. This is super easy to do! Simply put your finger/s inside yourself and check that you can feel the strings. They should be somewhat coiled around your cervix. If anything feels a bit strange, you should contact your doctor. 

Frequently Asked Questions

What causes the mirena coil to fall out?

t’s not really known what causes the mirena coil to fall out, but women who haven’t had children, have heavy periods and are under the age of 20 are more likely to experience mirena expulsion. However, this shouldn’t put you off having one fitted as it’s one of the most reliable forms of long-term contraception. 

Can the mirena coil fall out without you knowing?

It’s unlikely that you won’t realise if your mirena coil has fallen out. You’re likely to experience heavy bleeding and painful cramping whether your mirena is expelled or dislodged. If you can’t feel your IUD strings, visit a doctor immediately. 

How often does the mirena coil fall out?

In a study of women who had the mirena fitted directly after a vaginal birth, 8% of women experienced complete IUD expulsion after 6 months. Women under the age of 19 are more likely to experience mirena expulsion, as well as women who have recently had medical abortions.
