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!

(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.

I decided to invest in the Caya diaphragm since I was determined to find a non-hormonal method I could use that wouldn’t impact sex too much (I get irritation with condoms and the copper coil moved out of place pretty much immediately). I really wanted it to work but unfortunately it was way too uncomfortable during sex. It feels like there’s just way too much ‘stuff’ inside me. And I think it obstructs my natural wetness (I suspect that’s why some people mention a lot of discharge upon removal). My partner also said while he could definitely feel it, it wasn’t uncomfortable. I’d choose condoms over the diaphragm unfortunately. Hope this helps :)

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!
Very positive mood

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.

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.
