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've had an entirely positive experience using Natural Cycles. While using the impant I was struggling with acne, mood swings, irregular periods. And since swapping to use Natural Cycles I've felt much better in myself, my periods are very regular, I feel I understand my body and cycle so much more, and my skin has cleared up. In 5 years of using it it's been 100% effective at preventing pregnancy, I'm very careful to measure consistently, and I use the Oura Ring to help get accurate readings. But this small effort seems like a small price to pay in exchange for getting rid of all the nasty side effects of my previous contraception

I experienced irregular periods, major mood swings and no sex drive at all. Would not recommend this at all.

Insertion isn't pleasant, but once it's in place, there's nothing to do for years! I had my first Mirena coil over 8 years ago and haven't had a period since insertion, only very occasional spotting (maybe once every 3-6months). I know some women like to track their cycle, but I never think about it and prefer it that way! Would recommend.

The threads disappeared on the first coil so had it changed early (wasn't great as they had to go digging about to find the threads). Had another put straight in at the time thinking it was a one off but the same happened with the second so I had it removed early as soon as I noticed them becoming shorter to avoid the first scenario again and switched to the implant. Great that my periods stopped on it and it's super low maintenance though.

Extremely painful insertion. Blood loss continuously for about 3 months, bleeding everyday. Then periods became irregular, passing clots the size of my palm. Periods worsened after merina, when ironically merina was prescribed for heavy periods. Dermatitis caused by merina after 2 months. Told that results with merina are variable, and to wait and see. Not good advice considering the health issues and extreme blood loss caused by merina so far.

I mean as a contraceptive it works because I haven’t gotten pregnant. A positive my periods are extremely light and irregular, but as a distant irregular. But my skin has never been so worse in my life, I constantly have big deep spots on my chin. I used to have quite dry skin but now on the oily side.

The mirena coil stopped my periods and worked as a contraceptive, however it stimulated hair growth on my face which was not there before. As a result I have required many courses of laser. I do not have PCOS and have had testing, however I think the hormones in the mirena coil started the changes that are now continuing despite having the coil since removed. The coil was also extremely painful to have inserted.

Had the Mirena Coil in for around 9 months and it's made my periods so much lighter but a bit more irregular. It was really painful upon insertion and I'm still getting stabby cramps around when I should be having my period. Overall, I think it's worth it because my periods are so much lighter.

I had three Mirenas over the course of about 9 years. The first two were perfect, with no side effects and stopping my periods. For me the insertions and removals were fine. Maybe a 3 out of 10 pain wise and some mild cramps afterwards. Unfortunately I know that's not everyone's experience. After about 3.5 years of each Mirena, I got lots of breakthrough bleeding and my GP decided to change it early to prevent this. Unfortunately my third Mirena gave me unpredictable bleeding for months, which was affecting my life as I was always worried I'd bleed through clothes or during sex. I also kept getting recurrent thrush, which I'd not experienced before. For me another negative was that the strings always seemed to be really prominent and my boyfriend could feel them during sex. Overall a mixed experience - after years of hassle-free birth control I eventually changed to the POP due to the unpredictable bleeding I was getting with Mirena.

I found that when I got it inserted I had a light, almost discharge like period for 3 months and then once that finally went, I started having irregular periods and and someone whose always had regular periods this was infuriating. The reason I went on was for period pain and I found the pills, both mini and progesterone only, made my mood drop in terms of I was always angry and anxious and my general body image went on a downward spiral. I had no issues with the mirena up until about 3 months ago when all of this started happening again. I’m hoping this will help for others in my situation
