What is The Implant?
The contraceptive implant is a small, flexible rod inserted under the skin of the upper arm, releasing a steady, low dose of progestogen hormone to prevent pregnancy, mainly by stopping ovulation. It's one of the most effective contraceptive methods available, lasting up to 3 years, and is easily removed if you want to stop using it or become pregnant sooner.
It's a convenient option for people who prefer not to think about contraception daily or monthly. Changes to bleeding patterns are common, ranging from lighter, less frequent periods to more irregular bleeding, particularly in the first few months.
02 · Understand
Clinical context
Irregular bleeding is the most common side effect, and it varies unpredictably
Unlike some other hormonal methods, bleeding patterns with the implant can be quite unpredictable from person to person — some experience lighter or absent periods, while others have more frequent, irregular spotting, and this isn't always possible to predict beforehand.

Practical steps
The Implant Needs to Be Removed or Replaced Before It Expires
Contraceptive effectiveness isn't guaranteed once the implant reaches its expiry date (usually 3 years) — book a removal or replacement appointment before this time to maintain reliable contraception.
- 1Keep track of your implant's expiry date.This is usually 3 years from insertion, and a new one should be fitted or the current one removed by this time.
- 2Expect possible changes to your bleeding pattern.This is common and usually not a cause for concern, though it's worth discussing if it's bothersome.
- 3Check you can feel the implant periodically.This confirms it remains correctly positioned under the skin.
- 4See a doctor if bleeding changes are significantly affecting you.There may be options to help manage this while keeping the implant in place.
