Before you have an IUS fitted, you will have an internal examination to determine the size and position of your womb. This is to make sure that the IUS can be positioned in the correct place.
You may also be tested for any existing infections, such as sexually transmitted infections (STIs). It is best to do this before an IUS is fitted so that any infections can be treated. Sometimes, you may be given antibiotics at the same time as fitting an IUS.
It takes about 15 to 20 minutes to insert an IUS. The vagina is held open, like it is during a cervical smear test, and the IUS is inserted through the cervix and into the womb.
The fitting process can be uncomfortable and painful for some women, especially if you haven't had children and your cervix isn't stretched. You may also experience cramps afterwards.
You can ask for a local anaesthetic or painkillers, such as ibuprofen, before having the IUS fitted. Discuss this with your GP or nurse beforehand. An anaesthetic injection itself can be painful, so many women have the procedure without.
Irregular bleeding and spotting are common in the first six months after having an IUS fitted.
Check-ups
Once an IUS is fitted, it will need to be checked by a doctor after three to six weeks to make sure that everything is fine.
Speak to your GP or clinician if you have any problems after this initial check or if you want the device removed. Also speak to your GP if you or your partner are at risk of contracting an STI as this can lead infection in the pelvis.
Feeling unwell after having an IUS fitted
If you feel unwell, have pain in your lower abdomen, have a high temperature or a smelly discharge after having an IUS fitted, see your GP or go back to the clinic where it was fitted as soon as you can. You may have an infection.
How to tell if an IUS is still in place
Once it is fitted, an IUS has two thin threads that hang down a little way from your womb into the top of your vagina. The GP or clinician that fits your IUS will teach you how to feel for these threads and check that the IUS is still in place.
Check your IUS is in place a few times in the first month and then after each period or at regular intervals.
It is very unlikely that your IUS will come out, but if you can't feel the threads or if you think the IUS has moved, you may not be fully protected against pregnancy.
See your doctor or nurse straight away and use extra contraception until your IUS has been checked. If you've had sex recently, you may need to use emergency contraception.
Sex
Your partner shouldn't be able to feel your IUS during sex. If he can feel the threads, get your GP or clinician to check that your IUS is in place. If you feel any pain during sexual intercourse, go for a check-up with your GP or clinician.
