It is effective and it's convenient but unfortunately the side effects are really bad but it depends on different body types

This is pretty good for preventing pregnancy and my periods are thankfully gone, but now I have acne after having years of clear skin. It’s hormonal acne too due to the progesterone in the injection, so a nightmare to get rid of. I was prewarned about this issue but still hate it. I feel like my mood has gone lower too and I am more irritable than usual. Unsure whether I’ll get it again I will probably go back to the Lucette pill as that completely cleared my skin.

Caused me horrendous hunger such that i couldn't feel satisfied with any amount of food. It was terrible for me. And the side effects continue even after stopping. It was my first time in 11 years to back to hormonal contraception and l will never ever do it again. I only go non hormonal. I honestly can't take the risk.

took the bandage and plaster off to let the area breathe. (Added new plaster on the second day then removed it once I was sure that the bleeding stopped/wopuld stop. Noticed some bruising, but nothing too bad. A bit of clear, yellowish vaginal discharge No other issues so far!

I feel really happy about my experience on the implant. The first 6 months while it settled in were hard, I had a month long period then no bleeding since then. Emotionally speaking I cried every day for the first 6 months, then it was like a light switch went off and I've been fine since! Towards the end of my 3 years I started to get some break through bleeding so had it changed and a new one put in about 3 months earlier than expected but this was no trouble. I have been on it now for 4.5 years and would recommend to everyone but I know I've been lucky having no bleeding at all. I am looking to get off hormonal contraception and want to regulate my cycle to hope to have children in the next few years and want to experience a normal hormonal cycle so this is the only reason I'm changing from the implant! Overall I've had a really great time on the implant and feel reassured while being on the most effective form of birth control against unwanted pregnancy- which is a nice plus for the implant!

Normal for me I’m a U.S. bodybuilder nothing has change a lot of women gain weight because it can be an appetite enhancing affect. I’ve stayed the same tracking calories my spotting is normals as other off and on some missed periods and most lighter and little do not heavy. Experiencing hard sore nipples. And depression seems more there but not to bad. Do feel tired though out the day.

Used this for 1,5 years and I love it. The implant completely stopped my period this whole time, except 1 small break-thru bleeding 1yr ago. Insertion was not painful. Started using due to painful periods. Now living pain-free!

Positives of the Nexplexon implant is it is a very effective contraceptive and the insertion was quick and painless. However, I have been constantly bleeding (spotting and heavier bleeding) since I had it inserted 6 months ago. I have had bad cramping and lower back pain along side the bleeding. My overall mood has been effected as I feel exhausted most of the time, although I do work some night shifts so this may be a contributing factor. My sex drive has been lower than normal. I have noticed my boobs ache and feel sore. I am considering having it removed, if the bleeding does not settle.

I believe it ruined mindset, mental health and confidence. I am normally not over the top and this sounds like an exaggeration. Although I had a really tough year and these would've affected my perspective. I always have and would utilise those negative situations to motivate me and channel sadness into action. But when I was on the implant: - I had lost all confidence in myself and abilities - My skin got worse and I have always had super clear skin - I had more hair than usual - I was super easy to agitation and struggled to regulate my emotions - I became anxious and depressed (please note some of this would be situational and not just the implant). I thought it was all situational. Until I got it removed a month ago. I am still in the process of my hormones regulating which has been difficult. But after a month I am slowly finding my personality coming back. I am not isolating as much. I am channelling my energy into action and turning my life around again! I feel more like myself day by day.

50/50 experience overall. My skin improved to the point where it is clear aside from the occasional hormonal spot. Definitely would recommend if you’re like me and always forget to take the pill daily. I don’t get periods but when I do I bleed for about 2-3 weeks heavily. I have noticed some weight gain but nothing to be worried about. My boobs have grown 2 whole cup sizes. No mood changes as far as I’m aware. The implant insertion process was quick and painless so nothing to worry about there.

Due to a family history of thrombosis I was advised against the combined pill which at the time was still the most common option, so the implant seemed a good choice. Whilst it was convenient in that it was long lasting and easily fitted, with no horrendous side effects, with the conversation about choices becoming more open I realised that I had been putting up with side effects which were gradually getting me down - irregular bleeding and low libido (possibly connected!) made regular sex with my partner less easy and fun than it should be, and I found that the more I exercised the more I bled, and I wanted to exercise more. I decided to switch to the copper IUD to experience a normal cycle again without the hormones, and am very happy I changed.

Ever since using this form of contrception i get twice my period in one month and feels like stabing pains now and then in my stomach but not all the time. I was recommended the implant after i had my miscarriage Moody sometimes but other than that i guess its safe to have the implant in like its said everyones body is different
