Nexplanon is over 99% effective, making pregnancy while using it extremely rare but still possible.
Understanding Nexplanon’s Effectiveness
Nexplanon is a small, flexible implant inserted under the skin of the upper arm. It releases a steady dose of etonogestrel, a synthetic hormone that prevents pregnancy. This method is highly effective, with a failure rate of less than 1% during the first year of use. To put it simply, fewer than 1 in 100 women using Nexplanon will get pregnant within a year.
The implant works primarily by stopping ovulation — meaning no egg is released to be fertilized. It also thickens cervical mucus, making it difficult for sperm to swim through and reach any egg that might be released. Additionally, it thins the lining of the uterus, reducing the chance that a fertilized egg could implant.
Despite these powerful mechanisms, no contraceptive method is foolproof. So, can you get pregnant on Nexplanon? The answer is yes, but the likelihood is incredibly low.
How Often Does Pregnancy Occur With Nexplanon?
Pregnancy on Nexplanon is very rare but not impossible. Clinical studies show pregnancy rates around 0.05% to 0.1% per year of use. This means about 5 to 10 pregnancies per 10,000 women using Nexplanon annually.
Most pregnancies occur due to:
- Improper insertion: If the implant isn’t placed correctly under the skin or migrates from its original spot.
- Drug interactions: Certain medications can reduce Nexplanon’s effectiveness by speeding up hormone metabolism.
- User factors: Extremely rare cases where hormonal metabolism varies significantly between individuals.
The good news: proper insertion by trained healthcare providers and avoiding interacting medications minimizes these risks.
Medications That Can Affect Nexplanon’s Effectiveness
Some drugs may lower Nexplanon’s hormone levels by increasing how quickly your liver breaks down etonogestrel. These include:
- Rifampin: An antibiotic used for tuberculosis.
- Carbamazepine and Phenytoin: Used for epilepsy and seizures.
- St. John’s Wort: A herbal supplement often taken for depression.
- Some HIV medications.
If you’re taking any of these, consult your healthcare provider about alternative contraception or additional protection methods like condoms.
The Science Behind Pregnancy Prevention With Nexplanon
Nexplanon’s contraceptive power lies in three main actions:
- Inhibition of ovulation: Etonogestrel suppresses luteinizing hormone (LH) surge necessary for egg release from ovaries.
- Cervical mucus thickening: The mucus becomes thick and sticky, blocking sperm movement through the cervix.
- Endometrial alteration: The uterine lining becomes thin and inhospitable for implantation if fertilization occurs.
These combined effects create multiple barriers against pregnancy. Even if one mechanism fails (e.g., ovulation happens), others reduce chances of conception.
Nexplanon vs Other Hormonal Contraceptives
Nexplanon outperforms many other hormonal methods in terms of reliability because it eliminates user error like forgetting pills or patch replacement delays. Here’s a quick comparison:
| Method | Typical Use Failure Rate (%) | Main Reason for Failure |
|---|---|---|
| Nexplanon Implant | 0.05 – 0.1 | User error minimal; insertion issues rare |
| Oral Contraceptive Pills (Daily) | 7 – 9 | Missed pills or delayed intake |
| Contraceptive Patch | 7 – 9 | Patches falling off or late replacement |
| IUD (Hormonal) | <1 |
This table highlights why many choose Nexplanon for long-term contraception without daily hassle.
The Reality: Can You Get Pregnant On Nexplanon?
While incredibly effective, no birth control method guarantees absolute protection except complete abstinence. So yes, you can get pregnant on Nexplanon — but it’s exceedingly uncommon.
Pregnancies reported during Nexplanon use often fall into two categories:
- User-related issues: Implant not inserted properly or removed early without switching methods.
- Biological exceptions: Rare cases where ovulation occurs despite hormone levels meant to suppress it.
It’s worth noting that most pregnancies happen soon after insertion or removal periods when hormone levels fluctuate.
Pregnancy Symptoms While Using Nexplanon
If you suspect pregnancy despite having Nexplanon implanted, watch for symptoms such as:
- Mild spotting or bleeding different from your usual pattern.
- Nausea or morning sickness-like feelings.
- Tender breasts or unusual fatigue.
- A missed period if you previously had regular cycles before implantation.
Since irregular bleeding is common with Nexplanon users due to hormonal changes, don’t rely solely on spotting as an indicator—take a pregnancy test if concerned.
Nexplanon and Pregnancy Risks: What Happens If You Conceive?
If pregnancy occurs while using Nexplanon, immediate consultation with a healthcare professional is crucial. Although limited data exists on risks to pregnancy outcomes with an active implant in place, some considerations include:
- Ectopic pregnancy risk: Though rare, any contraceptive failure slightly raises ectopic pregnancy chances where embryo implants outside uterus.
- No proven birth defects link: Current research hasn’t shown increased birth defects due to etonogestrel exposure early in pregnancy.
- Nexplanon removal advised: To reduce potential complications and allow normal pregnancy progression.
Prompt medical follow-up ensures appropriate care whether continuing or terminating the pregnancy.
The Process After Confirming Pregnancy on Nexplanon
Once pregnancy is confirmed:
- Your provider will likely perform an ultrasound to confirm location and viability.
- If intrauterine pregnancy is confirmed, they’ll recommend removing the implant promptly to prevent complications.
Removal involves a simple outpatient procedure under local anesthesia. After removal, hormone levels drop quickly as the body adjusts back to natural cycles.
Lifestyle Tips to Maximize Nexplanon’s Effectiveness
Though highly reliable by design, certain habits help maintain peak effectiveness:
- Avoid interfering drugs: Always inform your doctor about all medications and supplements you take.
- Keeps scheduled checkups: Regular visits ensure implant remains properly positioned and functioning well.
- Avoid self-removal attempts: Only trained professionals should insert or remove the device to avoid complications affecting efficacy.
- Add barrier methods when needed:If taking interacting meds temporarily or unsure about implant status, use condoms as backup protection until clarified by your doctor.
These practical steps minimize chances of accidental pregnancy even further.
