Hormonal coil (IUS)

Women ask us lots of questions about getting a hormonal coil fitted – so we’re working on everything you ever wanted to know about the coil to help cover everything. If you want anything in particular covered, please contact us at info@theldown.com. In the meantime, we’ve summarised a few key points below:

• To get a coil fitted you need to go to a GP surgery or sexual health clinic where some staff are trained to fit them. You can contact your GP and ask if they fit coils, or search for clinics that fit coils here.
• The hormonal coil can be fitted at any time during your monthly period cycle, as long as you’re not pregnant (although you may prefer to get it fitted when you’re not on your period).
• Your doctor or nurse will do some tests to make sure that you can have the coil – like making sure that you’re not pregnant and checking for STIs.
• During your coil fitting, a doctor or nurse will use a speculum (like when you have a smear test) to open up your vagina and then insert the coil through the cervix into the womb. Most women find this uncomfortable.
• If it’s fitted in the first seven days of your cycle, you’ll be protected against pregnancy straight away. If it’s fitted at any other time, you’ll need to use condoms or other contraception, for seven days afterwards.
• You may be asked to go back for a check up 3-6 weeks after getting it fitted. You will also be taught how to feel the threads which hang down through the neck of the womb into the top of the vagina – this is how you know the coil is in place.

• Your hormonal coil can be removed at any time by a trained doctor or nurse. It’s normally simpler than having it fitted – they will gently pull on the threads and the T shape folds up and it can be pulled out of the womb.
• If you’re not having another coil put in and don’t want to get pregnant, you’ll need to make sure you don’t have sex seven days before you have it removed, or use condoms. Alternatively speak to your doctor or nurse about switching to another method.
• Check out our survey results to see how other women found their experiences with the hormonal coil.

• There’s a small risk of infection after the coil has been fitted which may lead to pelvic inflammatory disease (PID). Contact your doctor if you have unusual or smelly discharge, abdominal or pelvic pain, a high temperature or chills. 
• Sometimes coils can fall out, be pushed out of the womb or move. This is most common in the first few weeks after getting it fitted, or during a period. You may not know this has happened so it is important to check your coil threads regularly. If you cannot feel the threads or are worried your coil has fallen out or moved, contact your doctor or nurse and use condoms or avoid sex until then. 
• Very occasionally the threads get lost. This is more commonly caused by the threads being pulled up inside into the cervix. They may notice this when you go to have the coil removed, and sometimes the threads can reappear naturally.
• If the coil doesn’t work and you get pregnant, there’s also a small increased risk of ectopic pregnancy – when the egg implants outside the womb, normally the fallopian tubes. However, the overall risk of ectopic pregnancy is less in women using a coil than in women using no contraception at all.
• Rarely the coil may go through the wall of the womb when it is put in. This is called ‘perforation’ and if this happens, you may need surgery to remove the coil.
