For Birth Control "Getting Nexplanon was the WORST decision I have ever made. Decided to trust the research I did - which was all from the drug company and Planned Parenthood. When I first got it, I was severely bruised for two weeks, my whole arm was swollen and painful, and the whole time I had it, it would poke inside my arm, which was very uncomfortable. I was always scared it had moved. I was so anxious that I had to stop intakeing caffeine. I would cry all the time for no reason, and I was so depressed I wanted to die. I gained like 30 pounds over the course of six months because the places I'd researched said that weight gain was not considered a real side effect. When I finally got this abomination out, it took MONTHS to get back to normal and for my hormones to settle again. This is NOT worth it. I am begging you, please don't get this, and read forums with people's real experiences if you do decide to do so!! Extreme weight gain is a very common side effect! I felt like I lost control. It was horrible."

"DON'T DO IT, SIS! I went on Nexplanon about 2 years ago, and these have been my side effects: 1. Unrelenting cystic acne. 2. Extremely long periods - sometimes up to a month. 3. Extreme anxiety and depression - THIS WAS THE WORST - I suddenly felt suicidal. I tried very hard to fight this on my own. I deleted all my social media accounts, limited phone time, was deliberate about music and TV, and spent time with people who I felt were good for me. No matter what, I would cry. Everything would trigger me - books, TV shows, compliments, EVERYTHING. I was always sad, I would look in the mirror and just start crying. Meditation didn't work, my positive affirmations didn't work, going vegan didn't work, avoiding alcohol and coffee didn't work, getting dressed up, or doing things I loved didn't work. The only thing that worked was taking it out. I have had it out for two weeks now. I still have the acne and some of the weight gain, but suddenly I can cope. Don't do it, sis!"

For Birth Control "I got Nexplanon in Aug 2018. Honestly, the worst birth control experience I’ve had. I have month-long periods (with only 3 weeks in between cycles), complete with cramping, bloating, and irritability for the entire duration. My anxiety and depression have skyrocketed, along with suicidal thoughts. I get severe migraines now (never had in the past), my sex drive is completely gone, and I’ve been getting horrible acne on my face and back (also didn’t have in the past). I feel constant fatigue. I gained 20 lbs in the first 6 months of having it and can’t seem to lose the weight no matter how hard I try. And on top of all, recently I’ve started getting shooting pain around the site of my implant, and my whole arm feels numb and weak when that happens. I’m getting it removed in 2 weeks because I cannot continue with all of these side effects."

For Birth Control "The worst experience of my entire life!! I have always struggled with anxiety a little, but I have always been on some kind of contraception since an early age due to acne, and looking back, I don’t think the hormones ever really helped my anxiety. But this time last year, I was so happy, the happiest I had ever been. I then got the implant, and the nightmare of side effects started. • extremely emotional • thrush • extreme acne/oily hair • low libido • EXTREME anxiety • awful intrusive thoughts • weight gain • my arm where the implant is itches constantly. I never write reviews, but I don’t want anyone to feel how I have for the past 10 months."

For Birth Control "First, I've spotted on and off with this birth control. Over a year of it. Second, I can't lose weight for anything. After diets, exercise, you name it I can't lose weight. I've been the same weight, maybe a few lbs more for a year. Third, I have no desire to be touched or even want to have sex. My sex drive doesn't exist. This all started when I got on this. I'm getting it removed this month. No other birth control has ever done this to me. It's not for me personally."

For Birth Control "I have had the Nexplanon implant nearly 3 years after having my son. Initially, I noticed that I started experiencing headaches, period pains but without the periods, and I thought I could bear this. I liked the idea of not having any periods for the whole 2 years, but as soon as I started to bleed, I noticed it was irregular. I didn't like this at all and sometimes noticed some blood clots. I remember at one point I had to go to the hospital for breathlessness, tiredness, and had never experienced this before. I have noticed I continue to get chest pains, and I have had muscle aches all over my body almost every day. I have also had panic attacks too. I have also gained weight, and I don't easily do. It's due to be removed in 2 months, but I am scared to get it removed because of fear of contracting Covid-19. Lately, I have become bloated, have pain in my left lower abdomen, and my breasts are sore. I have no idea how I can get this removed without risking my health. I want it out!"

For Birth Control "I love this birth control. I've been on the patch, the shot, and the pill. All had the same issue, when it was time for my period, they would last 2-3 weeks. Horrible. I decided to get Nexplanon. I've been on it for 10 months now. It is amazing. The doctor said there was a chance I would bleed through a little at the beginning. That wasn't the case for me. I haven't had a period since the day I got the Nexplanon put in. My face is so clear and perfect now. I did gain a little weight, I'm sure the Nexplanon had a little to do with it, or could it be all those cookies I've been eating at night? Haha. I love this birth control. If you're doubting it, don't. I doubted it for 2 years, and I'm kicking myself for waiting so long."

For Birth Control "I am one of the lucky ones that has an amazing Nexplanon experience. I've had it in my arm for 2.5 years now, and I haven't had my period at all that entire time. It's super discreet in my arm. I do feel it sometimes if I cross or lay on my arms in a weird way, but any slight discomfort goes away when I shift positions and stop messing around with it. I haven't gotten pregnant, and I've probably put it to the test a time or two by this point. I haven't had any weight gain or other negative side effects, but I usually don't get side effects from medications. I was on the pill for 2 years, and I never noticed any changes either. Overall, my positive experience is 100% worth getting a second one after this. Even if my next implant is a worse experience, I still think it's worth a shot. One pro that I considered while getting it is that I'd much rather have to get something taken out of my arm than out of my cervix if I dislike it, and I stand by that logic."

For Birth Control "Don't do it. This thing should come with a health warning. I have had the implant for 6 months and have bled every day since I got it, not even light bleeding that you could live with, heavy bleeding. My mood has changed, I am normally a very positive, easy-going person. Since having this inserted, I spend most of my days crying, getting angry-I am not an angry person-and feeling suicidal, and that is scary. It has got to the point where my two kids are even asking, 'Are you okay today, mummy? Why are you crying, mummy?' I have spent days just sitting, crying, or extremely anxious. I have contacted medical services to get it removed and have been put on a waiting list. Also, I have put on over 20 lbs, considering that I haven’t been overeating, and no matter what I do, weight does not shift. My advice would be to stay clear, the implant is purely awful and just not worth it."

For Birth Control "I’ve had the Nexplanon for about two years now. The insertion process for me was very comfortable and simple (only a little pinch and then some pressure). My period stopped completely, and I got slight bleeding every once in a while (not even enough to wear anything). Although I have been slowly gaining weight over the past two years. When the implant was inserted, I weighed around 150 pounds, I am now up to 180 with little to no lifestyle changes. My appetite is crazy, and once I start eating, I don’t want to stop. Recently, my back acne has had an extreme flare-up which doesn’t make sense to my normal skin. During the summer, I typically clear up due to the sun, but since I’m on my last year of Nexplanon, my acne is out of control. I rarely get period pains, but on occasion, there are cramps. I want to get it removed, but the coronavirus makes me nervous."

For Birth Control "I would not recommend. Has pretty much ruined my life. My periods have been going on for weeks, up to months long, along with brown, bloody, and liquidy discharge. I’ve had horrible mental health, including suicidal thoughts, worsened depression, anxiety, and obsessive thoughts. I’ve had mood swings and gained around 5 lbs even on a healthy diet and exercise every day. My 'you know what' has had a horrible smell. I’ve tried everything from medication, figuring out my pH level, wearing cotton panties, to taking showers often, and still, there is a very bad odor, especially from my discharge and period blood. The cramps are debilitating, and I couldn’t even walk. The application area has ached ever since I got it, and I’ve had migraines constantly. If your body is sensitive to extreme hormonal changes, you have depression or any mental illness, or sensitive in general, I would not recommend this. It has been the worst experience of my life, getting it removed soon."

For Birth Control "I got this in July. I started my regular period when I got it inserted, and my period escalated to soaking through a pad every 10 minutes. I took birth control pills to fix this. I bled for 2 months straight like a normal period. Now I always am spotting, some days heavy flow. I usually always feel crampy now. I gained 10 pounds within two weeks of having this, all in my stomach. I always have migraines. I get more pimples and am always tired. I randomly get sad and angry for no reason. Also, my sex drive has been slowly but surely diminishing. I am keeping it only because it's keeping me baby-free."

For Birth Control "I absolutely love Nexplanon. I got it inserted in July 2013. Since then, I have had one extremely light period that lasted two days. I have no experience with weight gain. I have always had very little acne, and Nexplanon did not cause my acne to increase. I also haven't experienced any changes in moodiness. I recommend Nexplanon to my friends all the time. I also have a friend that has it, and she really likes it, although she has experienced some weight gain. I am very surprised so many people have had such a terrible experience. If you are considering getting Nexplanon, do not let these horror stories scare you away. Everyone has a different experience, so you'll have to see if it's a good birth control option for you."

For Birth Control "This is my 3rd insertion of the Nexplanon and will be removing it indefinitely as soon as possible. I noticed on the 2nd insertion that my moods were out of whack, I gained a lot of weight, and towards the end of the cycle, I felt myself again. After a month of my 3rd implant, I again feel noticeable moments of sadness and anger for no reason!!!! My husband confirms that it’s an off/on switch with my moods, and he doesn’t understand why. This is not worth it... I will gladly pop out another kid if it means not dealing with this terrible birth control method."

For Birth Control "DON'T GET NEXPLANON. It has brought me nothing but misery. I’ve experienced tremendous weight gain, acne, depression and anxiety, back and breast pain, headaches, brain fog, and fatigue. It’s been extremely hard trying to find a Planned Parenthood to remove the implant during the COVID-19 pandemic. I’ve been placed on a 2-week to 1-month waiting list and haven’t been contacted for almost 4 weeks now. I’ve also talked with a friend who has it too, and she’s been having the same side effects. My friend also found in her research that Nexplanon hasn’t been tested on plus-size women. And I’ve also noticed when speaking with other users of this drug that each person’s implant expiration is a couple of years off. Mine is supposed to last for 4 years, my friend's for 7, and I’ve heard 5 or 6 for others, and we all have the exact same implant. Not enough research, super crappy side effects, and too much negligence from providers. Just take the pill."

For Birth Control "I have had this for about 2 and a half years now. It has really taken a toll on my life. I’m either feeling sad or mad. I have no sex drive. The weight gain is ridiculous, I gained 20 pounds since being on this birth control. Losing weight is so hard, I can work out and fast, and I only lose a pound. I didn’t have a period for the longest time, and now I randomly have my period or spotting. I can’t even track it properly because it’s a mess. Don’t get me wrong, if you can handle all of this, then this is a product for you. The birth control part of it is great."

This birth control has made my life purely awful! I got it implanted in 2016! It was fine until the 6 months! Regular monthly 4-5 day periods, minimal acne, no weight gain, NOTHING!! Then all of a sudden, I changed into a different person. NEVER in my life even knew how anxiety felt, never recalled having depression. CRAZY ABSURD THOUGHTS! Literally feel like a psychopath! Let's not mention I’ve gained 50 pounds! I feel disgusting! I have mini panic attacks! I’m pure evil to my boyfriend. I don’t even want to leave the house. I have anxiety about EVERY LITTLE THING! Nexplanon was the worst decision of my life! I’m completely done with birth control. I have it removed next month on the 11th, and Lord, I wish that day would hurry up and come!"

For Birth Control "Do NOT get it!!! I got the Nexplanon inserted a year ago, and I'm getting it removed next week. It has been the worst experience, both physically and especially mentally. I gained 10 pounds and am constantly bloated, and I am someone who is a very healthy eater and regularly exercises. My skin also plummeted, and I now have painful acne. I am also bleeding CONSTANTLY!! I'll go for 3 weeks bleeding and 1 week not bleeding. Finally, my mental health has completely spiraled!! I have constant mood swings and waves of anger that have been completely ruining what are supposed to be special moments. I have zero control over my emotions and reactions, as if my brain and body are separate! I'll be telling myself I'm angry and crying over nothing, but I physically cannot get out of the terrible mood I am now somehow in. I am not myself anymore, and you are not alone if you feel this way with Nexplanon. I cannot wait to get this mood-controlling parasite of an implant out!!"

For Birth Control "First off: Please, please, please have your estrogen and progesterone levels checked before starting Nexplanon. It will save you so much time and trouble. If you have low levels of progesterone (like me), this will work miracles for you. However, if you already have high levels of progesterone, this might make you irritable, give you acne, cause weight gain, etc. (these are symptoms of having high progesterone levels). I've always had migraines with aura, so my birth control selection was limited to progesterone-only along with non-hormonal options. I haven't had a migraine since starting this, my adult acne has cleared up, my depression has lessened, and I haven't had any spotting or periods! But seriously, ladies, get those hormones checked!"

For Birth Control "I used Nexplanon back in 2014 after I gave birth to my daughter. It worked great the first two years, but once I hit year 3, I was bleeding nonstop. I couldn’t handle the bleeding anymore, so I got it removed. I recently had another one put in again in August 2020 and have been bleeding ever since. Maybe one or two days off every two weeks, but it’s been constant bleeding. I’ve also noticed an increase in hair loss. I’m emptying my brush every single time I brush my hair. Literally, handfuls of hair are gone. I also noticed that I have developed major anxiety. Specifically, “death” anxiety. I’ve never been paranoid of tragedies before. It keeps my mind going at all times. I’m also gaining weight little by little, and no matter what I do, I can’t seem to lose it. I’m hoping to get it removed this week so I could see a change in my overall health. After reading other people’s feedback, I’m realizing the effects of this birth control that I didn’t even think about as listed above."

For Birth Control "I am totally appalled by the lack of information regarding the side effects of this implant that is given to women before having it put in. The nurse I spoke to said nothing about negative effects besides the fact that it may interfere with my periods. It was simply made to sound like the best thing ever. Within a year, I had gained so much weight that I would be out of breath just walking down the road. After 2 years, the weight gain was so bad my GP put me on tablets for fluid retention. I didn't realize until last month, after coming across a TV show by chance about the lack of proper information provided to women regarding contraception, that the implant was to blame. After suffering from anorexia all my life, I am now obese!! And as for mood? I am in tears over everything, back on anxiety medication and antidepressants, as I have suffered from blood clots. I should not have been given it in the first place! BAN IT!"
