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

Benilexa coil  

I previously had the copper coil for 4 years because I wasn't keen on using a hormonal contraception but I wish I'd changed to benelixa sooner. I opted for a numbing injection during the procedure and hardly felt anything, it was great. Afterwards there was some very mild cramping and unfortunately I did get mild thrush within the week, however since then it's been amazing. Hardly any pain during periods and they are sooo much lighter. I used to bloat all the time but now I never do. I also lost about 4lbs and have stayed at that weight ever since. I had thinning hair previously and now have lots of new baby hairs coming in all over my head which I'm delighted about. Sex drive has decreased ever so slightly but not enough to be a problem. No changes to my skin or any other negative side effects. Really can't recommend it more, I'm delighted with not being in agony every month and I have much more energy since I'm only losing about a quarter of blood compared to before.

Benilexa coil  

I was told to take painkillers (paracetamol & ibuprofen) before the procedure which I did. For the procedure I had two lovely ladies who were supportive and talked me through all of the steps. I was offered pain relief including gas and air, so all of that was great. What I didn’t realise was the “bad period cramps” you are warned about were actually more like mild contractions, and having had a traumatic miscarriage a few years ago. The coil fitting unfortunately ended up triggering this trauma along with my anxiety, when I spoke to my GP they mentioned it was PTSD and that this can happen after a coil fitting. Afterwards the coil felt really uncomfortable for about 4 weeks where I could feel it inside me all the time and sometime it felt like it was scratching around in there! Also certain exercise & stretches were uncomfortable & often aggravated it leaving me in pain. My hormones were also all over the place on week 3 but that passed fairly quickly. I’ve had great support from the clinic and was referred to have an ultrasound to confirm it was in the correct place. On a more positive note I’ve only had one heavy bleed a week after it’d been fitted and no further bleeds and so far only spotting once. It’s now 11 months later and things have settled, so this is now working for me which is a relief.

Not 100% sure what to think yet. Enjoying not having to worry about administrating my contraception as it’s in there and working. However I am having unpredictable spotting, some emotional mood swings and often being bloated.
