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 have attempted trying the implant twice. Once when I was 18 and recently at 25 after having a baby. Whilst insertion is quick, easy and pain free with local anaesthetic, the effects of the implant on my mood have been detrimental. The hormone caused me on both occasions to develop severe anxiety and depression almost immediately after insertion, as someone who doesn't usually suffer with mental health issues. It's like having PMS but on an extreme scale. The implant on both occasions made my life miserable. I had to have both removed early and funnily enough a week or so after I did, I felt like 'me' again. The implant has a massive amount of hormone in that runs through your body daily. A hormonal coil works much better for me as it has almost 1/6th the hormone amount of an implant which is mostly contained within the uterus.

First year and a bit on the implant absolutely perfect. Minimal periods and literally zero side effects. However coming up to year 2 I started bleeding a lot on it. Almost every other week I was getting my period. My GP recommended I get a new one fitted and sadly from the beginning I’m still having frequent periods and ache. It’s a real shame as I really enjoyed having it at the start but I will be switching now.

The fitting was not as scary as I anticipated (helped by an amazing nurse!), and have had similar side effects to the progesterone-only pill, but without the stress of remembering to take it at the same time which is a nice break after years! 'Periods' come every few months generally for me, and are about twice the length of usual but less painful and none of the usual emotional disregulation leading up to it.

At first, my experience with the implant wasn't too bad as I was still 'wet' and moist, but over time my natural moisture has completely dwindled down to nearly nothing. This severe dryness is driving me absolutely insane because it honestly makes me feel like I have a post-menopausal vagina. Because of this, I am now changing back to the generic Desogestrel mini-pill, as I know from previous use that I at least had a normal, healthy white and milky discharge on that method. I am just stating my own personal experience here, and I still think that other people should definitely try the implant if they fancy a different form of birth control, because everyone's body reacts differently to the hormones. so yeah, thank u, next with the implant.

Been on the implant for 6 years now, initially I was spotting for 6 months before it finally settled. Now much more lighter periods so I can cope better as previously really heavy and needed tranexamic acid to manage, mood is more level now also, very rarely get cramps which is a bonus, have gained a little weight and body hair, overall happy with it
