The 5-Day Coil
The IUD '5-Day' coil is an emergency contraceptive which can be fitted by family panning clinics, sexual health clinics and some GPs.
What's involved?
A doctor or a nurse fits a copper intrauterine device (IUD) in your womb up to five days after you had unprotected sex, or up to five days after the earliest time you could have released an egg (ovulation).
How does the IUD work?
- It may stop an egg being fertilised or implanting in your womb.
Can anyone use an IUD?
Most women can use an IUD for emergency contraception. However, if you have been at risk of getting a sexually transmitted infection (for example by having more than one sexual partner or your partner having other partners) you could get a pelvic infection. You may have screening tests done at the time the IUD is fitted and you may also be given some antibiotics to prevent a pelvic infection.
An IUD may be suitable if you:
- are too late to take emergency pills (over 72 hours after unprotected sex)
- do not want to or cannot take progestogen
- want to use the most effective method of emergency contraception
- want the IUD as an ongoing method of contraception.
Where can I get an IUD?
Contraception (Family planning) clinics, sexual health clinics and some GPs fit IUDs. Sex Sense clinic DO NOT have the facilities for this. All the treatment you get is confidential and free.
How effective is it?
Very effective, almost 100%. It can also provide ongoing contraception if you want.
