How long can a period last on the implant?

If you are one of those who have decided to join me in the world of hormonal contraception, then buckle up because things are about to get bloody…literally. With so many options out there, it’s hard to decide which one suits you best. But if you’re reading this, then chances are that you’ve already narrowed your search down to a specific type of contraceptive implant: Nexplanon.

As they say – better safe than pregnant! So let’s dive into how long can a period last with the Nexplanon implant.

The Science Behind It

Before we jump into answering the question, let’s first understand how these little matchstick-like rods affect our menstrual cycle. On insertion, progestin is released from the rod and slowly enters our bloodstream over time. This hormone not only thickens cervical mucus but also thins uterine lining and prevents ovulation.

With no eggs being released every month (hooray!), menstruation eventually becomes irregular or may even stop completely (double hooray!). However, as with anything related to hormones (which can be inconsistent assholes) everyone reacts differently; for some women periods may continue regularly while others experience spotting or extended bleeding episodes.

How Long Can You Expect Your Periods To Last?

It’s difficult to give an exact number here since people differ in their experiences but expect anywhere between spotting for 9-15 months post-insertion (nooooooo), regular periods that only last 2-3 days (hallelujah!) or heavy bleeding that refuses to leave (cue fainting spell).

Here’s what we do know:

Immediately After Insertion

After getting your implant inserted into your arm by a health care professional/jack-of-all-trades person at any planned parenthood facility, expect continuous spotting for several weeks straight riding on four wheels with no stop in sight. Your body is just getting used to the hormones and preparing you for early menopause (whoop-dee-do!).

Within 3-6 Months

After several weeks of spotting, it’s possible that your periods will slow down as your body starts getting accustomed to the new method of birth control you’ve chosen. However this varies from person to person, some find that their period gets longer instead.

After A Year

This is when things start settling down a bit more permanently. Chances are good that by now you’ll have noticed fluctuations over time but overall bleeding will be less intense or shorter.

Managing Bleeding

You’re not alone if all these hormone caused irregularities leave you feeling “spotty” about Nexplanon (pun intended). The bleedings might make it difficult for daily life activities like intimate moments (guys we’re talking sex here), sports (imagine an uncomfortable situation during football practice), or anything involving white pants (S.O.S!!)

Here are tips on how to manage those pesky unpredictable bleeds:

  • Always use appropriate menstrual care products –tampons, pads etc.–to avoid staining.
  • Keep track so as to pay attention if there’s an abnormality outside what has already become normal/expected.
  • See a health care provider if ever experiencing severe pain, unusual vaginal discharge or blisters occurring around the implant site.

Bleed throughs/refusals from regular tampons can also happen because menstrual flow tends to be heavier compared before taking nexplanon contraceptive methods – put simply, it could keep flowing even after change.However alternative solutions such menstrual cups, Flex Disc technology) exist – they hold more than regular tampons while swimming with enhanced flexibility thus creating room for comfortable movement.

What If Your Period Doesn’t Stop?

While uterine lining thinning may cause bleeding episodes namely light bleeding and/or spotting for a shorter period, these are signs that the implant is working since they represent the protective factor important against pregnancy risks. If you aren’t experiencing anything beyond light to moderate bleeding then understand that it’s normal (happens to all of us at some point).

If however your period is persistently heavy/menorrhagic or stretching on months upon end then its important to go see a doctor as soon as possible because if there’s any persistent (heavy) blood loss, iron deficiency anemia can develop — fatigue, headache with pale skin/ nails characteristic come into play here.


When individuals look into Nexplanon/Radiopaque Insertion methods, many questions linger concerning how their menstrual cycle will fall in line after inserting. As this article has emphasized again & again,everyone heals differently, there’s no one way-off-the-cuff answer so anyone considering adoption should connect with healthcare professionals who can offer more insight regarding hormonal irregularity management.A better understanding leaves few things up in the air but worry not: because while we may lose control over our periods (who wants it anyway?!)but when implemented correctly nexplanon contraceptive technology rivals other choices both alternatively or otherwise!
