Mirena coil  

I was very worried about trying this method as I’d not used hormonal contraception before but overall it has been positive. The insertion was quite painful but not unbearable. It took about a week for me to recover, with me having to stop exercise for that time and then slowly increase again. Bleeding has been the most annoying part as my periods are very irregular now (previously they were regular as clockwork) and I have light spotting for up to a week before each period. But it’s getting slightly better each month and I’m hoping I’ll be one of the lucky ones who eventually gets to little or no bleeding at all. I’ve suffered no other symptoms of note.

Mirena coil  

I've had the hormonal mirena for 14 months now to reduce endometriosis symptoms. My periods have reduced in length (used to be 3 weeks) and happen irregularly and the pain has settled during these. I have however noticed continuous weight gain since I went on it, despite very little changing in my diet and exercise. I've always stayed at a very stable weight and now my breast have nearly doubled in size and my weight in general continues to creep up. I have tried upping my exercise with no improvement in my weight. I'm the heaviest I've ever been, except for pregnancy. It's a huge price to pay for a reduction in endo symptoms. It's very frustrating.

Mirena coil  

The insertion process wasn’t pleasant and I found very painful however I will say it was very quick and the pain didn’t last. After leaving the doctors I felt fine apart from a little light headed but that was due to me stressing. The next day if I didn’t know if had it fitted I would be none the wiser as I felt normal and had no issues. Since then I have really liked not having to think about it, I had no periods at all but have started to get a day or so of spotting once a month at the 18 month mark and some light cramps. The only other negative to me is that it’s meant that I now always have to use lube for sex as it’s definitely affected dryness. The best overall contraception I have tried

Nexplanon implant  

I originally had the implant inserted in May 2025, but I had a difficult experience with heavy bleeding. I had it removed and switched back to the mini-pill, which has always worked well for me. I decided to try the implant again and had it re-inserted around August 18, 2025. Here is the updated timeline of my experience: Initial Recovery (August 2025) • Wound Care: I removed the bandage and plaster early to let the area breathe. I applied a new plaster on the second day, eventually removing it once I was sure the insertion site had finished bleeding. • Healing: There was some minor bruising around the site, but nothing too bad. • Early Symptoms: I noticed some clear, yellowish vaginal discharge shortly after insertion, but no spotting or bleeding during this initial stage. Follow-up Symptoms (A few months later) After I had the implant in for a few months, I began experiencing some changes: • Spotting: I had spotting/light bleeding for a few days. • Discharge: This was followed by a period of reddish and brown discharge that lasted for a few weeks. Current Status Aside from that specific window of spotting and colored discharge a few months in, I have had no other issues. It has been working well since then, and I’m hopeful it stays this way!

Nexplanon implant  

(I had it inserted roughly around August 18th 205, and couldn’t remember how long ago it was when filling this out) , I 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/would stop. Noticed some bruising, but nothing too bad. A bit of clear, yellowish vaginal discharge No other issues besides having a bit of reddish and brown discharge for a few weeks after a few months of having it put in, I did try having it a while ago before August of 2025, say May 2025, had horrible bleeding and such, but then had it taken out and went on mini pill which has always worked ok for me, then decided to go back on the implant and have had it since then and no other problems, so let’s hope it stays this way.

Nexplanon implant  

Nexplanon has changed my life by taking away my PMS/PMDD mental health symptoms. I have a lot of trust in the evidence that it works effectively to prevent pregnancy. I found both the original insertion and the replacement to be non painful procedures. The replacement took a bit longer because it was fiddly for them to get the rod out. This was not painful but slightly uncomfortable but the nurses were so friendly that it was okay. It completely randomises my periods. I still get a slight breast tenderness before my periods which helps me to know when it is coming. It feels like my PMS is quiet and slow where as before it was fast and brutal. Recently after my new insertion I’ve had a bit of dizziness here and there, but I am still working out why… it could be due to my diet. Generally I prefer my experience on Nexplanon to what my natural experience was like and would continue to use it even if I stopped being sexually active.

Was previously on the progesterone only pill but did not want to have to remember it daily. Have had no issues with Nexplanon and had it changed recently after having the first for three years.

Nexplanon implant  

I would recommend getting the implant. There has been little to no difference in my body while using it and it has been a positive experience. I did notice my periods have gone from Light and regular every month to continue being light but very irregular and can last anything from 4 days to 3 months at a time. I also had one other negative experience a few weeks into having the implant. (I do think it was just my body adjusting as I haven’t had anything the same since). Where I was continuously being sick for 2 days, There was no signs of me being ill or have eaten anything unusual. I do think the implant has made very little changes to my body. Obviously a 3 month period is annoying but it does end you just need to be patient. I’m coming up to 2 years on my implant so I do feel as though my input is helpful as some people aren’t patient enough to wait out the symptoms like a long period.
