So, you’ve got a contraceptive implant and suddenly your period’s doing weird things, or showing up when you least expect it. Spotting between periods? Light bleeding for days? Wondering whether it’s your cycle or something else entirely?

You’re not alone. Spotting or irregular bleeding is one of the most common side effects after getting a contraceptive implant, especially in the first few months. But don’t stress, let’s unpack what’s going on and what you can do about it.

First Up, What’s a Contraceptive Implant?

This implant is a small, flexible rod (about the size of a matchstick) inserted just under the skin of your upper arm. It slowly releases a hormone called progestin to prevent pregnancy.

It’s one of the more effective birth control options out there which means you can pretty much forget about it once it’s in. That said, like any hormonal contraceptive, it can come with a few side effects, especially when it comes to your period.

Why Am I Spotting?

Let’s get into it. Spotting is light bleeding that can happen outside of your typical period window. It might be just a few drops here and there or something that lingers for several days. Either way, it can feel confusing - especially if your cycle used to be super regular.

Here are a few reasons spotting or irregular bleeding can happen after getting the implant:

• Your body’s adjusting to the hormones: When you first get the implant, your hormone levels go through a bit of a shift. It’s normal for your body to take time to settle, which can mean irregular bleeding in the first 3–6 months.
• Your uterine lining stays thin: Progestin thins the lining of your uterus, which is how the implant helps prevent pregnancy. A thinner lining means there’s less to shed during your period, but it can also make bleeding more unpredictable.
• The implant is working: Weirdly enough, spotting can be a sign that the implant is doing its job. Your hormones are being managed in a way that makes the uterus less hospitable for a fertilised egg, hence, bleeding changes.

Implantation Bleeding vs Period: What’s the Difference?

If you’re spotting unexpectedly, your brain might immediately jump to pregnancy. That’s where understanding implantation bleeding vs period becomes super helpful.

• Implantation bleeding is usually very light, often pink or brown, and lasts a day or two. It can happen around the time your period is due, especially if contraception fails.
• A period, even a light one, is usually more consistent in flow, lasts longer, and may come with the usual suspects - cramps, bloating, mood changes.

The key difference? Implantation bleeding is a possible early sign of pregnancy, while irregular bleeding on the implant is more likely a hormonal adjustment. If you're unsure, taking a pregnancy test can clear things up quickly.

Contraceptive Implant Side Effects:

In addition to spotting, some people experience:

• Headaches
• Mood swings
• Breast tenderness
• Acne changes
• Irregular periods - or none at all

These implant side effects often improve over time. Some people even stop getting their period altogether, which is safe while on hormonal birth control. But if symptoms become disruptive, it’s worth talking to your doctor.

Can Anything Be Done About the Bleeding?

Short answer: yes. If spotting is cramping your style (literally or figuratively), here are a few things to try:

1. Give It Time: The first few months are often the messiest. If it’s been less than six months since you had the implant placed, your body might still be adjusting.
2. Track It: Use a period tracker to note when and how much you’re bleeding. It can help you spot patterns and give your healthcare provider valuable info.
3. Check In With Your Doctor: If spotting is frequent, heavy, or just annoying AF, your doctor might suggest a short course of hormonal treatment (like the pill) to help stabilise things.

What If I’m Still Worried?

Totally fair. Spotting can feel unsettling, especially if it’s new for you. But remember, the contraceptive implant effectiveness rate is high. If you had your implant inserted by a professional and haven’t missed any major steps, the chances of pregnancy are low.

That said, it’s always okay to reach out to a healthcare provider if:

• You’re bleeding heavily for more than a week
• You’re getting cramps or pain that feels unusual
• You just want peace of mind

You’re Not Broken

Bleeding with a contraceptive implant doesn’t mean something’s wrong. It’s one of the most common side effects, especially in the early months. Knowing the difference helps you stay informed, and recognising what’s normal (and when to get help) keeps you empowered.

At the end of the day, it’s your body, and you deserve to feel comfortable and confident managing it.
