Before using FAM, I was using the copper IUD religiously for about 11 years. I had a mixed experience even if overall positive with it, but back in 2021 after a year of chronic yeast infections and finally discovering it had slipped, I decided to not replace it. In that time, my periods were always like clockwork and I was tracking my cycles in a few years leading up to this. Not just tracking the days, but my symptoms and body sensations as I entered into each phase. I was using a period tracking app called Eve, but I knew not to rely on it religiously, it was just for a rough idea of when my fertile times and period would be. I decided to just continue with this, because I had built such a deep relationship with my body and have no problem checking my cervical fluids. I used it until 2022 when we decided to try to conceive, and we conceived within a few months, even though sadly, it was ectopic. I wouldn't recommend this method to anybody without months of really knowing your body and listening to it-- learning your cues for when you know you're about to ovulate, roughly timing how long your follicular phase is, and it helps if your periods are regular. While apps can be really helpful, you have to do the hard work of building that relationship with your body. I wouldn't recommend it for somebody just starting out, or if your periods are irregular.

I had been on PoP contraceptive pill for nearly 10yrs, I have also tried CoC's and injection prior. I wanted to learn more about my body and be natural. This method takes a lot of research and understanding in order for it to work and be effective. I read books and watched YouTube videos to educate myself and joined FB/Reddit group. I use an app called read your body to input my temperature and other symptoms to track where I am in my cycle. It is all done manually by me and not relying on a system like natural cycles to do it for me as this is less reliable....Since stopping the pill my libido came back which is great and I feel emotions depending on where I am in my cycle. My Cycle regulated within 2 months after stopping the pill and for the past 3 years I have learned what is normal for me. My cycle is very text book 28 days long on the dot every month, I ovulate on day 15. This method works for me, I haven't gotten pregnant but on the days during my cycle I could get pregnant, we use condoms rather than abstaining. I would say it took me about 6 months to learn and feel confident in this approach.

I’ve been using NC since 2021, I use to love this app and tell everybody about it until I had sex on a green day and got pregnant. I used to think it would never happen to me as I’ll use the app right. Measured every day and was very religious with the app. However, I ovulated earlier and fell pregnant! The app only goes off previous ovulation compared to current meaning it doesn’t prevent pregnancy as yes you have red days but it’s just a prediction! For example green day on day 6 (had sex) and ovulated on day 10 (red days) and fell pregnant. Ovulated 5 days early! Sperm can live inside you for 5 days hence why I’m pregnant and will be getting an abortion.

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.

While I had my Levosert, I liked it. I had mood changes, and cried a lot more than usual, but mostly just leading up to my period so it was manageable. I had recurrent thrush with it, and actually ended up having a prescription for monthly fluconazole tablets. In the end, after around 2 years, my coil slipped into my cervix, and it was incredibly stressful. I had no symptoms that it had slipped down, except my strings were a bit longer than usual. A doctor mistakenly told me it was fine to keep using, but when I later had it checked at a different clinic with ultrasound, they were alarmed that I'd had no symptoms as it was pretty much almost out of my body. I'd essentially been unprotected for about 8 months, and this led to a big pregnancy scare.

The mirena coil did effectively reduce menstrual bleeding and prevent pregnancy. Due to thickening vaginal discharge I found I was more prone to thrush and also that this had an impact on arousal. I was an advocate for the hormonal coil until I changed to a non hormonal birth control and found that this had elevated my anxiety certain times in my cycle. I am epileptic without seizure control and this was my reason for coming off hormonal methods. Female hormones can trigger seizures in women with refractory epilepsy!

I was on the Kyleena IUD for 10 months after being on mirena for 5 years. Kyleena has had a terrible impact on my mental health and the reason I got it removed was because increased hair loss.

Have only had the coil for 2 months (although feels like much longer) so will give it a bit more of a chance, I also acknowledge that everyone reacts differently and my side effects seem to be less common, however in my experience and at this point in time, the negative side effects FAR outweigh the positives. My GP talked me into trying Mirena for managing my PCOS and the excruciating pain I would experience on occasion from burst ovarian cysts, as well as the birth control aspect. I’ve gone from an abnormally long (but fairly painless) cycle to an even longer one, bleeding and in moderate-severe pain almost daily. If my stomach doesn’t hurt, my head will be, or both. I’m not joking when I say I look pregnant from abdominal swelling on top of it all.

It was a very positive as i was having irregular heavy periods And personally I had a much better libido When in the past, bloods tested low in testerol levels of 7.5 i II wish this had been aware of of this before bow, i thought there was something not quite right as apparently 12 or above is the better level of testerol for women

I've had the Mirena coil for about 10 months now, my doctor recommended it to stop uterine polyps from reappearing. Prior to the coil I had very heavy, extremely painful periods and pretty bad iron deficiency, but now my periods are super light and not painful at all!! The insertion was painful but not worse that the period cramps I used to get before; I spotted for 3 months straight but after that I started having semi-regular periods. I noticed that I had much more energy (probably because my iron levels were back to normal), my libido increased and I lost weight. I am really really happy with the coil.

Awful experience having it fitted, very painful. I’m convinced it triggered vaginal atrophy (I was already menopausal)

Recurrent abdominal pain and pressure in my lower tummy. The only positive thing is that it has stopped heavy periods
