Copper coil (IUD)  

Changed from mini-pill after 16 years as I wanted to know my body without hormones and start to understand my cycle better. No issues with the copper IUD. My periods are a bit heavier but they are more predictable and regular. I do have more cramps but they are manageable. Insertion was fine, just uncomfortable. I was surprised how quickly the cramping started after though. I was in quite a bit of pain for an about a week as it settled in.

Copper coil (IUD)  

I genuinely love my copper coil (IUD) that lasts 10 years, and I wanted to write this review as I used to hear horror stories about it and it almost put me off, but I didn't experience this and I want to reassure others that may be considering this. I got my copper coil in March 2023 after an unwanted pregnancy as a last resort. No hormonal contraception worked for me and I often experienced negative side effects, so I felt my last attempt was the copper coil. What a GREAT choice! Yes, the insertion is uncomfortable, but I asked for cervical numbing cream and it was mildly uncomfortable for two minutes. Definitely bearable with numbing cream. Since then, my periods are still regular a little bit heavier. and I do get a few more cramps. Very easily managed with a menstrual cup and painkillers. I love not having to think about my contraception, and I don't need to think about getting it replaced for TEN years. What a dream! It's a life saver for those of us that struggle with hormonal contraceptives.

Copper coil (IUD)  

As the copper IUD gets so much negative press I wanted to post my genuine positive experience. Initially I was apprehensive to get the coil after hearing so much fear mongering, and so many users saying they had major cramping (perhaps some did), but this wasn't the case for me. I experienced the worst period cramps that I have ever had within the first 7-10 days post-insertion, but it was manageable with ibuprofen + heating pad. Once I got through those initial days it practically subsided (apart from the slight numbness around my cervix from the procedure which healed around the month marker so I recommend taking any kind of sex slowly to avoid worsening it). Between days 10 and my first period I had occasional mild cramps here and there, but after that first period the cramps completely subsided. Fast forward to month 6 I can confidently say that the cramps only occur at normal times of the month (just before or the first days of your period) just slightly more painful but not unbearable. When it came to bleeding side-effects in the first 3 months I never got any spotting between periods and my period came on time but was heavier than usual (more bleeding but the same number of days as without an IUD). However after that 3 month marker I remember the bleeding becoming lighter, to the point now where it is similar if not the same as the amount pre-IUD. In conclusion the IUD has worked great for me, and I barely even notice it now. If you can do visit a sexual health clinic over a GP surgery, as they seem to be more experienced. Please don't let peoples bad experiences put you off, I strongly believe that for 99% of IUD users the bad experiences are based upon people noticing the fine details with their body that perhaps was there before but now that they have the IUD they become a 'worrier'. That every little cramp means something bad. I say that if you have an issue, go and see a professional who's qualified and not ask the internet.

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.

Nexplanon implant  

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

Nexplanon implant  

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.

Nexplanon implant  

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.

Nexplanon implant  

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.
