Copper coil (IUD) vs Cap or diaphragm

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 was having heavier periods

I’ve enjoyed using the cap around my fertile window but struggle to feel 100% confident I have inserted it correctly. When removing the cap I notice a lot of discharge but not after use, only when removing. Way better than the pill or condoms for me.

Apart from the issue I'm currently dealing with (it getting stuck inside of me), I LOVE the diaphragm. I found out I wasn't never fitted (which is why it kept getting stuck upon removal), so my new, awesome doctor actually sized me. It's easier than popping in a tampon once you learn how to do it and then ya pop it out the morning after sex. No side effects, no hormones, no emotional hangover. It's very hard to find though. Pharmaceutical companies don't want women to buy one silicone object that lasts for the rest of your life, so finding the right size and actually getting it has been a challenge. My mom used it and only got pregnant to have me (her only child) and I've been using it for 5+ years with no issues.

I've used Caya several times over the past couple years (they last up to 2 years- due for a new one now). I use it on the edges of my fertile window (with fertility awareness) and/or combined with withdrawal or condoms to boost efficacy during the fertile window. Always use with Caya/Contragel- they come with an applicator to re-insert the gel into the vagina, as you need to reapply the gel each time you have sex. Watching the YouTube instructions on how to put it in (plus the instruction manual in the box!) helped me understand how to use it properly and to have an idea of how it was inserted properly.

I used the caya cap. It has been a game changer after previously taking the pill. I feel in control, no need to remember to take a pill, just put it in when needed. Better than condoms as it is women based and not detectable. Effect of not taking hormonal contraceptives has been amazing. All the side effects that I had ( migraines, reduced sex drive, dryness, breast tenderness, strong period pains, breakthrough bleeding and emotionalness) all gone. I wish someone had told me about it before!

Having experienced terrible physical and mental health side effects from both types of contraceptive pill (Combined and POP), and permanent pain and repeated UTIs with the copper coil, I hoped that Caya diaphragm would be a suitable non-hormonal method to try. Unfortunately, I found insertion very tricky - it seems I have a case of "deep vagina, small fingers", as I could never tell whether I'd pushed the diaphragm up far enough to cover my cervix, and sex was always a bit uncomfortable. I'm naturally prone to cystitis and thrush, and getting both while using the diaphragm also put me off using it long term. However, on the plus side - I didn't get pregnant (though I was still breastfeeding a lot, and my periods hadn't yet returned postpartum), and I did manage to avoid the hormonal depression, skin changes and weight gain/loss that I've experienced in the past with pills.

All in all it was acceptable

Fiddly and a faff. Didn’t bother a couple of times and ended up pregnant. He’s nearly 20 now and I’m still married to his father so not all bad :) Tried the copper coil for a bit after but it gave me very heavy periods and stomach cramps which had never been a problem before. Switched to the mirena coil and now on my third - no periods for 15 years and no menopausal symptoms despite being 52. What’s not to like?

I was only using it shortly, as I wanted to avoid hormones. It was not bad, but the need of using a spermicide as well was the reason why I stopped, I had vaginal discharge caused by the spermicide.

After bad experiences with the pill I wanted to avoid hormonal contraception, and did not think the coil was right for me. The diaphragm is therefore the only method of contraception (other than condoms) that I found available. I got it fitted at a local sexual health clinic fine - although I did have to ring up to request that my appointment was with someone trained with fitting it, as not everyone can do this. There were a few different sizes to make sure you get one that fits you. It's a bit tricky to get the hang of putting it in and taking it out at first, but if you're used to fiddling with a mooncup you'll pick it up. It's good when you have planned when you need to use it, as you can insert it a couple of hours before and not have to worry about it in the moment. My partner says he can feel it but it's usually not uncomfortable for him - occasionally when I'm on top. As someone who has had a lot of UTIs, I was a bit worried about the increased risk of cystitis (because the rim sits against your bladder) but have never got it when using the diaphragm. The downside is that it requires a bit of extra planning, so if I'm lazy I end up just using condoms instead. Also it's pretty gross when you take it out after leaving it in overnight, and a load of stinky semen-spermicide goo comes out! All in all, a bit of a faff but I'd way rather use this than hormonal contraception. I only use this occasionally as a result. I wish there was a really good non hormonal, non coil option out there!

Tried the pill in my early 20s but didn’t like the side effects, felt generally unwell and slightly “down” while taking it. Started using the cap in my mid-twenties, first one fitted at the wonderful Marie Stopes Centre, but subsequent ones refitted after two preganancies by my (female) GP. Used it for about 25 years until menopause (apart from gaps to have children). Brilliant if used properly with gel or cream, no side effects, and means when you want to attempt a pregnancy your body doesn’t have to adjust to your normal hormone levels as it does if you take the pill. Pregnant within 3 months of trying for both my preganancies.
