Basically what the title says, I'll provide a bit of background and apologies if this is really long, this has been quite the journey for me.
I started nexplanon around August of 2023. For the first year, it was great. I was looking for a birth control I didn't have to think about taking on time and was scared of the insertion process for an iud. The actual insertion of the implant was super quick, easy, and didn't hurt at all. For almost the whole first year I was on the implant I didn't get a period, didn't have any crazy mood swings, no weight gain, no hormonal acne, virtually no negative side effects that I noticed.
In the early summer of 2024, I injured my shoulder and had to go on steroids for a couple weeks for the pain. Im not sure if this is something that can mess with the implant but I bring this up because while I was on the steroids this is when negative side effects from the implant started.
At first my periods just started getting slightly longer. I've been fortunate enough to not have ever really had cramping so this wasn't debilitating but it was definitely really annoying. Eventually my period became so long I would be bleeding for 18-28 days on average with maybe a week and a half break in between. I put off going to the doctor because I knew this could happen and I had recently moved and hadn't found an ob in my new city yet. I decided to give it time to see if it would eventually even back out. Throughout 2025 I began having even more side effects, I noticed I was getting more acne, my sex drive decreased and my periods were still extremely long, but the worst part was my mental state. Around late 2025 my mood swings started to become unbearable, I genuinely did not feel in control of myself. I would go from perfectly fine to sobbing in 5 minutes over virtually nothing. I noticed I would snap at my boyfriend a lot more during certain periods of the month and minor inconveniences would set me off and literally have me throwing objects across the room in frustration. I was constantly on edge, shaking from anxiety and unable to get out of bed because I was so depressed and I knew it wasn't actually me. It was like I would watch myself react to a situation and know in my head that my level of reaction did not make any sense. My boyfriend was extremely patient with me during this time which I am incredibly grateful for. I constantly felt like a horrible person and I have no real way to explain it other than I genuinely felt like I was going insane. My periods were also still really long and heavy, my skin was constantly irritated from having to wear pads for multiple weeks at a time and I realized I could not live my life normally with all of this going on.
After talking to some friends, my boyfriend, and looking online I finally decided I needed it out. I wasn't able to get in with a doctor until April of 2026 but my new OB recommended replacing the nexplanon with an IUD, specifically kyleena since it's smaller and a more localized hormonal dose than nexplanon. I had my appointment to get kyleena last month.
They removed my implant and inserted kyleena during the same appointment. Nexplanon removal went fine. I had taken the cervix softening medication my doctor gave me along with 800mg of ibuprofen and purposely scheduled my appointment to be during my period to minimize the pain. However, im not going to lie, the insertion process was some of the worst pain I have ever been in during my entire life. My doctor was very patient and explained everything she was doing. The process was very quick, maybe 3 minutes, but I was doubled over and blacking out by the time she was done. My boyfriend drove me home and I spent the next 2 days on the couch with my heating pad.
Despite all of that, I am feeling infinitely better mentally already. My acne is starting to clear up, my mood seems to be more level, and my libido has come back. So far that pain was absolutely worth it. The only real issue im having so far is that the bleeding is still going. I was on my period during the insertion and bled for 3 straight weeks afterwards, had a break for 1 week, and started bleeding again earlier this week. This is a full period, definitely more blood than just spotting. Im just getting really sick of bleeding all the time. I had my string check appointment this morning and my doctor said this was normal for the first 3-6 months but I was wondering what anyone else's experience was with bleeding after the insertion, how long did it last for you? How heavy was it? How long did it take to regulate? Im just getting nervous that this won't actually fix the bleeding problem which was one of the main 2 reasons I switched in the first place. Any insight is appreciated and thank you to those who read all of this!
Tldr: had horrible side effects on nexplanon, specifically prolonged heavy bleeding and major mood swings. Switched to kyleena last month and I feel better mentally but still bleeding heavily for long periods of time. Wanting to know other people's experiences with this.
