Contraceptive Ring

What is the Contraceptive Ring?

The contraceptive ring, also known as the vaginal ring, is a small, flexible plastic ring that is inserted into the vagina and releases oestrogen and progestogen. These hormones work by:

  • Preventing ovulation, so no egg is released.
  • Thickening cervical mucus, making it harder for sperm to reach an egg.
  • Thinning the uterine lining, reducing the chance of implantation.

The ring stays in place for three weeks and is then removed for a one-week break, during which you have a withdrawal bleed (like a period). After the break, you insert a new ring.

Who is the Contraceptive Ring suitable for?

The contraceptive ring may be a good option if you:

  • Prefer a once-a-month contraception method rather than a daily pill.
  • Want a highly effective and easy-to-use option.
  • Experience heavy or painful periods and want a method that can regulate them.

However, it may not be suitable if you:

  • Are over 35 and smoke, as this increases the risk of blood clots.
  • Have a history of blood clots, high blood pressure, or migraines with aura.
  • Are uncomfortable inserting and removing the ring yourself.

How does it work, and what are the options?

The ring is self-inserted into the vagina and left in place for 21 days. You then:

  • Remove the ring and take a 7-day break, during which you will usually have a withdrawal bleed.
  • Insert a new ring after the break, repeating the cycle.

Alternatively, some women skip the ring-free week and insert a new ring immediately to avoid having a period. Other contraceptive options include the contraceptive patch, combination pill, or mini pil.

The contraceptive ring offers several advantages for people seeking a low-maintenance and effective form of birth control:

  • Over 99% effective when used correctly.
  • Only needs attention once a month, making it more convenient than daily pills.
  • Can make periods lighter and less painful.
  • Works even if you vomit or have diarrhoea, unlike the pill.

Before starting the contraceptive ring, it’s good to be aware of some common side effects and safety notes:

  • Does not protect against STIs, use condoms if needed.
  • May cause temporary side effects, such as nausea, breast tenderness, or headaches.
  • Some women experience vaginal irritation or increased discharge.
  • There is a small risk of blood clots, similar to the combination pill.
