For many women, a contraceptive implant offers a set-it-and-forget-it kind of convenience. But like any medical device, it can sometimes develop issues that require a professional's attention. Knowing what's normal and what's not is key to staying safe and getting the most out of your birth control.
Here are three specific warning signs that suggest it's time to contact your healthcare provider about your implant.
1. You Can't Feel the Implant (Or It Has Moved)
After insertion, you should be able to gently feel the implant as a small, thin rod just under your skin. Your doctor will tell you to check for it periodically. If you suddenly cannot find it, or if it feels like it has shifted to a different spot, this is a red flag.
A non-palpable or migrated implant could mean it has been placed too deep, or it has moved from its original position. While rare, a migrated implant can travel to a blood vessel or deeper tissue, reducing its effectiveness or causing injury. If you can't locate it, do not panic—but do call your provider immediately. They may use an ultrasound or other imaging to confirm its location. You should also use a backup method of birth control (like condoms) until the implant is found and cleared.
2. Signs of a Local Infection or Skin Reaction
Any redness, swelling, pain, or pus at the insertion site that is not improving—or is getting worse—is a sign of a potential infection. While some bruising and mild tenderness are normal after the procedure, these symptoms should fade within a few days.
If the area becomes hot to the touch, feels increasingly painful, or you see any discharge, see a doctor promptly. An untreated infection in the arm can become serious and may require antibiotics or even removal of the implant. Similarly, if the skin over the implant becomes very itchy, blistered, or starts to peel (a possible allergic reaction or skin irritation), it's worth getting checked out.
3. New or Worsening Migraines (Especially with Aura)
Hormonal contraception, including the implant, can influence your migraine patterns. The implant releases progestin, and for some women, this can trigger new headaches or make existing ones more frequent and intense.
A particularly important warning sign is the onset of migraines with aura—visual disturbances like flashing lights, blind spots, or zigzag lines that precede or accompany the headache. Migraines with aura, when combined with hormonal birth control, are linked to a slightly higher risk of stroke. Even if you don't have aura, if you develop any new, severe, or persistent headaches that feel different from your usual pattern, tell your doctor. They may recommend switching to a non-hormonal method or a different type of hormonal contraception.
When to Seek Emergency Care
Most implant-related issues are manageable, but a few signs warrant immediate medical attention:
- Shortness of breath, chest pain, or coughing up blood – these could signal a blood clot (deep vein thrombosis or pulmonary embolism).
- Sudden, severe pain in your lower abdomen – this may indicate an ectopic pregnancy, which is rare but possible.
- Yellowing of the skin or eyes (jaundice) – this can be a sign of a liver problem.
Your contraceptive implant is a highly effective form of birth control, but it's not a set-it-and-forget-it device. Being aware of these three signs empowers you to take action quickly, ensuring your health and the implant's continued effectiveness. If you have any doubts or concerns, always err on the side of caution and call your healthcare provider.
