Many women seek long-term contraception to avoid unplanned pregnancies. Birth control implants like Nexplanon have surged in popularity due to their convenience, effectiveness, and low-maintenance nature. Many individuals turn to options like Nexplanon not only for reliable pregnancy prevention but also to manage menstrual cycles and reduce period-related symptoms.
Nexplanon is a small, flexible implant inserted under the skin of the upper arm. It releases a steady dose of the hormone etonogestrel, which prevents ovulation and influences the menstrual cycle. While it is highly effective for contraception, its impact on periods varies from person to person, with some experiencing lighter or irregular cycles and others having no periods at all.
In this article, we will explore how Nexplanon affects menstrual cycles, including whether it can completely stop periods, and what users can expect.
Key Takeaways
- While Nexplanon doesn’t always stop periods completely, many women experience changes to their menstrual cycle, including lighter, less frequent, or even absent periods.
- Irregular bleeding or spotting is common for the first 6-12 months. Some women may stop having periods altogether, while others might experience heavier or prolonged bleeding at times.
- Over time, some women may find that their periods become very light or stop entirely, while others may continue to experience irregular bleeding.
- Not every woman will stop having periods on Nexplanon, and for some, periods may become more irregular or unpredictable instead of ceasing altogether.
- If changes in bleeding patterns are concerning or bothersome, it’s a good idea to talk to a healthcare provider to explore options.

Nexplanon and Menstrual Cycle Changes
Nexplanon is a long-acting contraceptive implant that releases a steady dose of progestin to prevent pregnancy. One of its most common effects is altering the menstrual cycle. Users may experience irregular bleeding, spotting between periods, heavier or lighter flows, or in some cases, a complete absence of periods (amenorrhea). These changes are generally harmless, but they can be unpredictable and may take some time for the body to adjust.
While these menstrual changes are among the most notable side effects of Nexplanon, some individuals also wonder, “Can Nexplanon cause weight gain?” Although weight gain is not a universal side effect, hormonal fluctuations from the implant may contribute to slight changes in weight for some users.
Types of Changes in Periods
When using Nexplanon for contraception, many users experience changes in their menstrual cycle. These changes can vary from person to person and may include:
- Irregular Bleeding: Spotting or light bleeding between periods, especially in the first few months, is common as the body adjusts to the hormones.
- Light Periods: Some women may notice their periods become lighter in flow, lasting shorter.
- Heavy Periods: In contrast, others might experience heavier, more extended periods during the initial months of use.
- No Periods: A significant number of Nexplanon users may stop having periods altogether after a few months, which is a common and generally safe side effect.
- Frequent Periods: Some women may experience more frequent, shorter cycles.
These changes usually stabilize over time, but it’s essential to consult a healthcare provider if bleeding patterns are bothersome or persist.
Hormonal Mechanism Behind Period Changes
Nexplanon releases progestin, a synthetic hormone that affects the body’s hormonal balance, leading to changes in the menstrual cycle. The hormone thins the uterine lining, resulting in lighter periods, less frequent periods, or no periods. It also thickens cervical mucus, making it harder for sperm to reach an egg, and suppresses ovulation in some users.
These hormonal effects can cause irregular bleeding or spotting as the body adjusts. Over time, many users may stop having periods altogether, while others may experience changes in flow or frequency due to altered hormonal regulation.
What to Expect for Patients
Patients using Nexplanon can expect changes in their menstrual cycle, including lighter periods, irregular bleeding, or possibly no periods. These changes are due to the hormone progestin, which thins the uterine lining and affects ovulation. Some may experience spotting or heavier periods, especially in the first few months.
Over time, many users stop having periods altogether. Communicating with a healthcare provider about any concerns or unusual bleeding is essential. While these side effects are common, they are usually temporary. Understanding how Nexplanon works can help patients feel more comfortable with these changes.
Conclusion
Nexplanon can affect periods, making them lighter, irregular, or even stopping them altogether. It works by releasing hormones that thin the uterine lining. Each woman’s body responds differently, so changes in the menstrual cycle are common. Understanding these effects can help manage expectations and ease concerns about period changes using Nexplanon.
