Copper coil (IUD) vs Progestogen-only / Mini pill

Seriously heavy periods (wearing nightime pads and a tampon and still bleeding through my clothes in like an hour) and sometimes extruciating cramping. A lot of spotting between periods also which I've never experienced before. Nurse has told me that the coil should not affect my bleeding and I've gone straight from the mini pill to this so it may have been that the pill was improving my regular symptoms more than I realised.

I chose to have the copper IUD inserted in January 2023 because I'd had a bad experience previously with the mini pill (mood swings, decreased libido, and vaginal dryness) and I wanted to try a non-hormonal contraception. The process of getting it inserted was one of the most painful things I've ever experienced with severe pain, cramps, and dizziness. The doctor and nurse I had were wonderful and very reassuring, which made the process slightly easier. I would however, highly recommend anyone thinking of getting it to ask for pain relief if it's available. I'm certain it would have made the process much better and less traumatic for me. What followed was 6 months of intense cramping and spotting at random times of the month and extremely painful, heavy, and long (between 10-12 days) periods (I was lucky to have very light periods before going on any contraception which is one of the reasons I opted for the copper IUD). After 6 months or so my periods settled down to become shorter (5-6 days) and more regular but remained extremely heavy with lots of dark blood clots and severe cramping/back pain - to the point where I would have to take days off work and couldn't exercise normally because I felt sick/dizzy from the pain. The severe cramps started like clockwork on the 7th day before my period was due and continued until the end of my period meaning I was having up to two weeks a month of severe cramping. I also experienced cramps and thick, brownish discharge/spotting around ovulation. Other than the heavy, painful periods, I experienced none of the mood swings, weight gain, or loss of libido that I'd experienced on hormonal contraception, so the copper IUD was great for that. If anything, I experienced a notable increase in my libido! I chose to have the IUD removed about two weeks ago, after just over two years, because I was finding it increasingly difficult to cope with the intensely painful cramps and heavy bleeding and I developed severe iron deficiency anemia, likely due to my heavier periods. I was nervous about the removal process after finding the insertion process so difficult but it was significantly less painful and super quick. I had some light spotting afterward and some minor cramps but nothing too bad. I'm yet to have a period after removal and I'm, so far, two days late (confirmed not pregnant). I would normally have had at least a week of intensely painful cramps by now but so far, nothing. Overall, the copper IUD was great at the times of the month I wasn't bleeding or ovulating and I liked not having any of the side effects that come with hormonal birth control, but it ultimately wasn't worth the heavy and painful periods/iron deficiency anemia for me!

This post is for those considering the copper IUD. I know it is scary and you can find many horror stories online, so I thought I make the effort and share my IUD journey with you which has been very positive. Insertion: Got the IUD on the 4th February Insertion was uncomfortable and for a few seconds very painful but it did go away very quickly. I did bleed a little bit as well but I always do when they are examining my cervix. I’m very sensitive down there. Note:I have never given birth and my GP said that it can be more painful for those who never given birth vaginally. The GP who did the insertion was absolutely brilliant. She talked me through what she was doing and she prepared me for the most painful part. There was also a nurse present who was literally holding my hand through the whole procedure. It was such a positive experience. I’m grateful for both of them for making this experience so manageable. Right after insertion: I wasn’t in pain afterwards - I only had a mild sense of discomfort like you would have after a smear test. I even went for an hour walk right after the procedure, so it was really not bad at all. Please note that I’m a physically active person, so walking for an hour doesn’t tax me much. Others might have different experiences and it’s absolutely fine if you just go home and rest in bad for the rest of the day. That’s what i was told to do to be fair. Days After insertion: The cramping was moderately bad after the next 4-5 days, spotting was light After the 4-5 days cramping intensified especially after exercise and at some point the pain made it difficult to walk. Never felt cramping like that before. It made me very irritated as well. Normal painkillers didn’t work, I had to take cocodamol to get some relief but it was short term. Later it turned out that it coincided with my PMS. I was bleeding everyday after insertion, so it was hard to determine what was menstrual bleeding or bleeding because of the IUD insertion. Around day 11 cramping settled significantly. I only had occasional cramps which don’t require pain killers. I think I got my period on day 12 (16th Feb or 15th Feb) because the bleeding intensified around that time. It is the 17th February today. Moderate bleeding (more than usual but moderate) very light cramping. Fast forward March. After my period in February, I did not experience anymore unusual cramping - even after exercise. I got my period on the 9th of March. I did have some light cramping and mood changes as PMS but nothing unusual. The cramping was very moderate and did not require painkillers. Bleeding lasted 6 days with 3 days of heavier bleeding -3 pads a day- which for me is heavy bleeding. I have had sex a few times since insertion and my partner couldn’t feel the strings, so no problem there. Did not experience any dryness and my sex drive during ovulation is definitely higher than when I was on the pill. Overall very happy with my wee copper coil. 😊 Just a reminder that negative stories often get more attention than they deserve—people are more likely to vent about bad experiences than take the time to share positive ones Will keep you updated!

Generally happy with this pill, which I'm now able to get from my GP. It's much better than Desogestrel for me. I haven't had a period since I started it and no breakthrough bleeding either. My skin is great on this pill and my weight hasn't changed - if anything I lost a bit of weight, which unfortunately made my boobs smaller. I read this pill has a diuretic effect but I haven't noticed that at all. Initially I had headaches and some disturbed sleep, but these went away after the first month. My sex drive is lower but not to the point of it being an issue. I love that it has the safety of a 24-hour window, plus it's made my mood really stable and has stopped my periods.

I have been taking Hana for 4-5 months now. Generally I have enjoyed the effects of taking a POP, but the specific effect Desogestrel had has led me to trying Slynd instead. Aside from the contraceptive effect, I mainly started taking this pill to combat low mood, hormonal headaches and to hopefully lighten my period. I did find all of these things improved on Hana, but I found that inconsistent and increasingly frequent bleeding was killing my sex drive, making it a touch redundant and prompting the switch. I would have likely reluctantly kept taking Hana (or tried a different brand) as I do feel my mood has benefited overall, and it is advised that bleeding can settle down over time, but now that Slynd was finally available in the UK, I see no need to compromise. In my first month on the pill, I had no bleeding at all (as you would expect). I also generally didn't notice many other side effects. I did have some mood swings - which took me by surprise, but were easier to handle once I identified what was happening and generally settled down after the first month. I also noticed slight vaginal dryness (not uncommon for me in my luteal phase and nothing a bit of lube can't fix) but have been unable to determine if this has also settled. As I got to the last week of pills in my first pack, I had a withdrawal bleed, which again was not unexpected. I was pleased to note that this was much lighter than my normal period, even if it lasted longer, because I could essentially just wear period underwear instead of my normal underwear and that would last all day. In my second month, I noticed some light but otherwise entirely manageable spotting. This alone would not have dissuaded me from taking this pill. I again had a withdrawal bleed around the start of the last week in the pack and would have been happy with that cadence. This is where the problems started, however. Through the course of the third month, I noticed that the light spotting was turning into more prolonged bleeding, which by the end of the month was almost constant and in some cases led me to leak through my clothes. Having done some research online, I decided to try taking two pills instead of just one - this did seem to make the bleeding lighter but it has continued. While I feel that the hormones have overall had a positive impact on my sex drive, it is very hard to feel attractive or think about sex when you are constantly bleeding.

I have been on this pill for 4 months. My periods are regular which is the ONLY good thing about it. My skin is awful, bloating is insane. The bleeding is heavier than I’ve ever experienced and my sex drive has completely disappeared. Everyone’s experience is different but personally, this is the worst pill I’ve ever tried.

3-6 months: (started the pill on 14/10/2024. I've done a review on my first 3 months so this is a follow up) Day 126 - 17/02/2024 – I’ve pretty much had 2 back to back periods with a 2 day break between which I really didn’t appreciate. They really hurt and I convinced myself something was wrong. I have made a doctors appointment to talk through everything. I’m just fed up with bleeding all of the time. I’m spending SO MUCH on pads it’s ridiculous. 12/03/2025 - I’m on my second week of my 6th month of the pill. I’ve kept having back to back periods and consulted the doctor. Because I’m coming up to 25 I had a routine smear (that came back clear) and the doctor did a pelvic exam and they recon it’s the pill that’s the cause of all the bleeding (which I assumed it was anyway. But better safe than sorry). I’m fed up of the bleeding but they’ve given me 6 more months after this to see if it settles. If not we’ll switch to something else. 5/4/2025 - I’m coming to the end of my 1st week in the 7th month of the pill. All I can say is that I’ve stopped bleeding/spotting for the most part. It’s been about 3 weeks since I last bled. So I guess the doctor was right. However, I had like a 1 day period at the beginning of the week it was painful and some period blood and then nothing since. But the last couple of days I’ve had some cramping as if a period wants to start but hasn’t yet. Overall, I think we’re getting back on track hopefully. Sorry I didn't reflect as much but it's pretty much been the same sort of story for the past 3 months

Since taking the zelleta pull my mood has gotten a lot worse. I catch myself crying over little things I would have never cried about before. I used to take the cerelle pill which worked well for me but now I get irritated easily and lasch out at my boyfriend a lot.

Never have had a pregnancy scare (touch wood). I’ve been on Noriday for at least 5 years now and affect trying 2 different BC’s and another mini-pill, this is by far the best off.

I’ve been on this pill for about 4 years now and I wouldn’t recommend it to anyone. Periods come and go when they please (at least 2/3 times a month) and can last for weeks on end. I tried to change to Desogestrel after a trip to the doctors but that made me throw up for 5 days straight. I’m limited to what pills I can take due to family history so I’m stuck with this until I can find an alternative, only plus side is is haven’t fell pregnant once whilst on it.

I wanted to come on here to write this review and want people of the potential side effects of this medicine. I have experienced a really negative change in general outlook, mood and self worth and completely put it down to this pill. I have today thrown it in the bin after becoming so down that I couldn’t function. I have been on this pill before & for a lengthy stretch, but this time (after having a child) has been completely different and utterly awful. At the start of taking it my periods were quite constant, but they did get lighter and more manageable on this pill. If the mood change wasn’t so bad I would still take it but it’s not worth it at all

I have been on Cerazette for 4 years now. Initially, I had headaches, breast tenderness and mood swings. These symptoms subsided after 3 months. My periods became very irregular and then stopped altogether. Although my doctors deny this all the time, I feel like the pill caused excessive weight gain. Yes, I have had circumstances that affected my life but the weight gain was dramatic. In the first year alone, I gained 15 kilograms. After 4 years, I am up to 25 kg extra weight (BMI 29) and I am struggling to lose the weight with diet and exercise. Lately, I have had more bodily hair growth and am losing some hair on my head. Not many mood swings but definitely feeling angry most of the time. I am also struggling with a very low sex drive, which is starting to affect my marriage. I have an appointment with my GP, will try to switch to the combined pill to try.

This pill stopped me from getting pregnant and that was the only good thing about it. Constant spotting, sore nipples, and decreased sex drive. Now on norgeston and so much happier!
