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.

Having used the pill on and off for 20 years I was hesitant to use another hormonal contraception but I was so happy with kyleena - no noticeable mentsl or physical symptoms. Insertion is not pleasant but it's over in seconds.i experienced some period cramps in first few weeks but then periods became extremely light and pain free for the last 3-4 years. I would get this method again without hesitation.

I had a terrible experience with Mirena. It started with severe cramping after insertion. The cramping continued for weeks. I got a UTI from it. Then the other symptoms started - severe depression, sneezing, severe sinus pain, insomnia. I experienced severe vaginal dryness and vulvodynia (shooting pain down there) which ultimately led me to showing up at my gp and begging for it to be removed.

Periods stopped, no noticeable side effects other than toward the end of the 5 years when I had a few side effects (tender breasts, spots, mood swings) which I put down to hormonal change as the coil was coming to expiry date. Now I've had it replaced and I have no side effects. Stable mood, skin clear, no periods, no stomach/back/head pain.

In terms of contraception practically perfect, I react extremely badly to hormonal contraception usually and this didn’t cause any of the negative side effects I usually get from hormonal methods. My periods became lighter and I still have the normal symptoms of my cycle which is exactly what I want. The only negatives (which is quite a big one) is significantly increased pain throughout my cycle, during my bleed and also cramping randomly throughout the month, sometimes when exercising and also two days before my period which I didn’t experience before. I am devastated that this has been discontinued in most places. I think it’s completely inexcusable that there is now no IUS which for most people doesn’t stop their period. One other slight negative at the beginning was my partner took some time to get used to the feeling of the strings when having sex, however this improved after a few months and is no longer an issue.

Got this inserted as a long-acting, reliable method of contraception. I found the insertion process ok, it was uncomfortable but not painful. I was able to easily feel the coil threads when I checked regularly. I had lighter periods but actually found period pains worse with the coil in place - hence the deducted star. I had this removed as we wanted to try to concieve. The removal process was totally painless. We got pregnant in one month of trying.

Overall my experience has been positive in comparison to my previous experience with combined oral contraception. I no longer have mood swings or night sweats however over the 4 years of having my hormonal coil I now have no sex drive which was a big change for me, in addition to this sex became painful.On the other hand my periods stopped after 6 months to a year.

Today I finally had my Mirena coil removed. The insertion and removal went smoothly and were painless. I had the coil for 10 months. During the first 6 weeks, I experienced continuous bleeding. After that, my periods became more regular but were very long up to 10 days and lighter than usual. After a period ended, I had another one a week later for only 3 days, and then the cycle repeated exactly every 28 days. I also had persistent discharge, infections, and cysts, and I even had to have a biopsy due to white spots on my cervix caused by the Mirena. Today, having it removed, I felt immediate relief. I was prescribed desogestrel tablets, so hopefully it will be better, although the pill doesn’t have very good reviews either.

From coil insertion I had issues, it was very painful having it inserted and I had cramps for a weeks. I also got a post coil infection. I would get horrible period pain at that time of the month and my periods would also last longer than before coil. Often had spotting and could always feel there was something there like a pressure (difficult to explain). I also didn’t feel like myself, I didn’t have energy for a long time after the coil insertion. I got thrush and then got a UTI in August which I had for 6 & half weeks and took 5 courses of antibiotics. I finally saw a nurse who said stop the meds and agreed with my decision to have coil removed and said we would monitor it. I had coil removed 29/09 and am still getting the discomfort down there and regularly have a hot bean bag on my lower abdomen. Some days are better than others and this week I have had headaches so I’m not sure if it is linked to coil removal. The nurse will call me for follow up next week and if still getting it she needs to see if it could be pelvic inflammatory disease

I liked that it was minimal effort once inserted. My periods were far lighter and less frequently occurring. Because of the thickening of vaginal fluids being part of the mechanism; I found I because much more prone to UTIs after sex and also had lower sexual drive. I came off the Mirena because I wanted to track my cycle accurately to see if my hormones and cycle were affecting/triggering my seizures (I have drug resistant epilepsy). When I came off the Mirena I found I was less anxious over the months following swapping to the copper coil I.e. non hormonal. This had not been a concern of mine when on it.
