Coil Fittings.
How to know if a coil is right for you, and what to expect from your fitting.
Are you considering a new coil?
Please make sure you have considered your choice of contraception and whether you feel an IUD (copper coil) or IUS (Mirena coil) is suitable for you. You will probably have had a discussion with a doctor, nurse or midwife.
You may have been advised to have the IUS (Mirena) coil to try to help with heavy periods. This needs to have been discussed with a GP or gynaecologist who will have determined whether you need any blood tests or an ultrasound scan before recommending this.
Please read the information leaflets for your chosen type of coil:
If you have never had a baby, have only had babies by Caesarean section, or have had surgery to the cervix there is no reason for you not to have a coil but please arrange a telephone appointment with one of our doctors before booking a fitting.
If at this stage you have further questions please do either arrange an appointment or book a phone call with one of our doctors.
Changing your existing coil.
If the previous coil fitting was straight forward you may book a coil change with the Sexual Health Clinic. If you are having a change of coil please abstain from intercourse or use additional contraception for 7 days before the change.
Emergency Contraception.
You may have been advised or chosen an IUD as emergency contraception. The IUD can be fitted up to 7 days after unprotected intercourse to prevent pregnancy.
If this is the case please phone to speak to your local Sexual Health Clinic on 0300 123 1731.
The fitting appointment.
To arrange a fitting, please contact the local Sexual Health Clinic on 0300 123 1731.
Timing the appointment in your cycle.
An IUD can be fitted at anytime as long as you are certain you are not pregnant. You will be protected immediately.
An IUS can be fitted at anytime as long as you are certain you are not pregnant. If it is fitted in the first seven days of your cycle you are protected immediately. If it is fitted after this, you need additional contraception for 7 days.
Post-natal fitting.
This needs to be at least 8 weeks after delivery.
Problems with your coil.
Serious complications of the coil are uncommon however it is important that you know what to do if you have a problem.
Severe pain after fitting or at anytime associated with a heavy vaginal discharge, feeling ill or having a fever needs urgent assessment. A missed period with an IUD (not an IUS) also needs urgent assessment.
If the coil comes out or if you cannot feel your threads please use alternative contraception and make an appointment with the Sexual Health Clinic on 0300 123 1731.
