Apart for heavy long periods, I Became mean and short fused. My sex drive is zero. I am less excited and feeling empty. Had the implant for 8 months, the behaviour changes are not settling.I am generally miserable and its damaging my relationship.

Safest and easiest contraception in my opinion. However does come with lots of side effects as any medication does, it is manageable but irritating at times (headaches, irregular bleeding every month and lower back pain). I also get rashes at the implant site quite frequently and heard this is very common- gets itchy but normal apparently

Of all the contraceptives I tried I was most satisfied with the implant. I had mostly no side effects and it stopped my period completely after 1 year (had some spotting irregularly in the first year). It was a very effective method, with painless insertion and changes (had 3 implants in 7 years). I removed it because I wanted to give my body a break before potentially trying for a baby. The main side effect and reason I took off one star is the loss of libido and vaginal dryness. My libido was very low and when I did get into sex, the dryness made things painful. Overall the sensation and pleasure of sex took a hit, but it was manageable. Now that I am off the implant I notice a resurgence in libido and feel more connected to my body and sexual self.

I had the implant for 19 months and got it taken out today after being a little fed up of the side effects. For the first couple of months, I had my period as normal and pretty much no other symptoms except being a bit more emotional. Then over the next year or so i had completely stopped bleeding and had no issues. Then I started to get migraines maybe 2 a week for a couple weeks (I had 5 in the space of a month?) and they were so unbearable. And then I started bleeding again but it was so irregular. I could have a period twice in 2 weeks but not have one for like 6-8 weeks and then get spotting for a few days. It was so frustrating. That and having incredibly sore nipples and tender breasts that I couldn’t wear anything without it hurting. Ever since getting it inserted I have gained around 30kg which is very noticeable on someone who is barely 5ft tall. So because of that my self confidence has completely dropped. It felt like I was buying a bigger bra every 2 months. And none of my clothes that I had a year and a half ago fit me anymore. Overall the beginning was pretty great but about a year in I didn’t like it anymore.

Really easy insertion process, nothing to be worried about as a local anesthetic is used. Luckily so far I haven't had a single bleed on this (touch wood) although I had this fitted 2 months postpartum and my periods hadn't properly come back yet. I kept forgetting to take my pill and so I love the implant so far as it's automated contraception that requires no effort for 3 years! Perfect for a busy mama!!!

At first stopped my periods for 1 year but after periods came back much lighter but at random times. Now periods are more regular and still light rather than random spotting. Recently the doctor found a cyst in my ovary they think was caused by the implant.
