My experience of the copper IUD is mixed, even if overall positive. I first got it as emergency contraception after my first sexual experience, and was not properly offered any pain relief. The pain was excruciating and slightly traumatic, but also as I wasn't used to things going inside my vagina either. However it served me perfectly for 5 years, and no hormones and side effects from those. When it was time for renewal I was prepared emotionally and knew what pain relief to ask for. The procedure itself was quick and felt very empowering. They offered me the 10 year one which was slightly bigger and I thought it was no big deal. I was in constant low level pain and discomfort with it, and periods became excruciating. I got it switched back to a 5 year one and this cleared up. Again. the procedure was fairly quick as I knew my body and had good pain relief. My last one suited me fine up until around 2020, when the combination of the stress from the pandemic and using an expired lube gave me recurring yeast infections that lasted at least a year. I then discovered that it had slipped and so got it removed, deciding to switch to Fertility Awareness Method. After that, the recurring yeast infections stopped.

Personally, I would never get another coil again. The reason for 2 stars is I actually had the copper coil inserted in 2018 and it was okay but I had it removed in 2021 after asking for it to be removed for over a year. My periods were heavier as expected, but I also had thrush every month, BV multiple times and it just became so uncomfortable dealing with this constantly. I had the copper coil again this year (march 2025) and it was awful. The insertion this time took an hour compared to the 10 minutes last time. I was in so much pain I was heaving, I have had three babies and this was worse than birthing a child. They finally got it in and I ended up with a mild infection probably due to how long and how many attempts it took. A week later it started to settle down 🤞🏼 however almost three months later and I'm having it removed next week. I don't know if it's misplaced (they will be checking this first) but I feel it 'stabbing' me randomly every day. I will be walking and suddenly stop and feel like it's stabbing me or trying to come out, but I can still feel the strings. On two occasions it's hurts me during sex which is a red flag. My periods are 10-12 days long and I'm getting through a pack of pads every 1-2 days, plus the thrush is back again. I was offered a replacement however I have declined and I am currently trying to decide which combined pill may be best for me, tho I am nervous about going on the pill now!

I had several fortnight long periods on this pill. My regular periods are horrific so I was initially willing to take any side effects the pill had, and even though my regular level of pain/vomiting/fainting went away, I barely had rests from bleeding, my mood swings and hormonal breakdowns were uncontrollable, I gained a lot of weight, and I still had nausea and cramping. After over 18 months the side effects still had not dialled down so I had to quit.

Nice to stop menstruation but in no way worth it for the awful psychological impacts. Mental breakdowns were indeed had.

Little to no very noticeable side effects, my anxiety definitely heightened but that was a personal predisposition. Overall very happy experience but swapping due to some low moods

Been on this pill for years and it has treated me well. I have lighter periods and they are a lot less painful. I have suffered very badly with acne over the years and although my skin is not perfect, it has been the most stable on this pill. I don’t find any other side effects to my mood or body that I notice.

As soon as I started taking it, my first period whist on this pill came after a week and it was the most horrible period I’ve had in my entire life (it was a longer period then I ever had before (with really heavy cramps constantly) that was the first step in the negative journey. After that, I continued taking it and my acne got worse especially on my back. I had thought it would improve but was much worse event at month two. After two months of taking this pill, I’ve also gained weight which I noticed straight away but had put down to temporary water retention but seems to not budge and have had extreme weight fluctuations like never before and been feeling very off and not myself ever since taking it/depressed, also have lost all sex drive. I am at the point where it’s either stick it out for another month to see if symptoms ease up or stop and cut my losses. I’ve decided to stop.

This was prescribed to me to help regulate my periods; however did the complete opposite and have made them worse. I have no clue when my periods are going to begin or end now, as well as if the bleeding will be light spotting or extremely heavy. I have become incredibly sensitive to many things that would never have bothered me pre-pill, as well have been bed bound due to negative mood changes that I have no explanation for. I have been sad before, however, these feelings I could not explain or combat so I have decided to switch pill.

My period was ok on it. My acne was very bad cystic nothing would get rid of it. Changed to Yasmin and I haven’t had cystic acne my skin is clearing. Hair thinned on top of my head too. This pill can cause high androgens which can cause bad hormonal acne and hair loss

This sent me nearly insane with my moods. I had no other side effects other than it made me nearly suicidal. I know you could say maybe it wasn’t the pill but I was fine before taking it, happy in myself, then after I had a mental breakdown I stopped taking it and suddenly felt like myself again. I’ve heard a lot of people say it’s been awful for their mood and I’m surprised they haven’t banned it yet

I’ve never had Thrush before and went on this pill 2 months ago and got it within the first 20 days of using it. I’ve also felt nauseas everyday since maybe the first week into it. Will symptoms subside? I really hope so. I havent bled but I was on the depo injection for the last year so its normal for it to take a while to bleed again.
