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 started using Natural Cycles a few years back. I was never on any birth control as a teenager as my mum didn't want my young body being put on hormones. However, once I settled down with my current long-term partner, I wanted to have the peace of mind that I wasn't going to fall pregnant. The first few years of using Natural Cycles were great and empowering, understanding the changes in my body and knowing when I had ovulated was great. What I had failed to understand was it predicted with its algorithm your date of next month's ovulation based on your previous month. Well. I managed to fall pregnant not once, but twice in the space of 8 months. The first time around, I thought it was my fault and I had not taken my temps properly (even though I never had an issue in the past). I had a surgical abortion as I was 3 months pregnant before I actually found out. I was willing to try again and really get to grips with it even though the clinic was very strongly advising me to go on some form of HBC. In the past 6 months, my body has recovered from the abortion and got back into its usual swing of periods and I saw I was ovulating again. This time around I invested in an Oura ring to pair with my NC app to be certain of my temps being taken. All was well, I stuck to my green and red days religiously. I use the pull-out method on red days (if we do have sex). And I trust our pull-out method completely because we definitely know he does not ejaculate inside of me or we tend to stick to oral sex rather than penetrative. I noticed my temperatures lately had been higher than usual and my ovulation was confirmed a bit earlier than usual. I didn't think much of it as I had stuck to our red days and green days as shown. When I went on calendar view, I saw that my fertile window just gone was a lot shorter than 6 days and I had unprotected sex (on a green day) that was 2 days before I ovulated. I did a test and indeed am pregnant yet again. I contacted NC straight away and got them to go through my data, which they did and have taken full responsibility for the muck up with their algorithm. I advise you to check your fertile windows and note any other observations (cervical mucus), because the algorithm cannot be trusted. And from what I now know, ovulation may change throughout different cycles (stress, sleep etc). I will no longer be using them ever again which is sad as I did so enjoy using it.

I like the injection as no periods at all but gained over 2 stone in weight and no amount of dieting, eating less or exercising helps loose any weight at all I just gain even more.

I didn't notice any changes at first. I got my period for the first month or two, then the bleeding was irregular and lighter and eventually it stopped completely. I gained weight quickly. I would get hungry even after eating. I would get severe vaginal itching a few days after the shot.

It is effective and it's convenient but unfortunately the side effects are really bad but it depends on different body types

This is pretty good for preventing pregnancy and my periods are thankfully gone, but now I have acne after having years of clear skin. It’s hormonal acne too due to the progesterone in the injection, so a nightmare to get rid of. I was prewarned about this issue but still hate it. I feel like my mood has gone lower too and I am more irritable than usual. Unsure whether I’ll get it again I will probably go back to the Lucette pill as that completely cleared my skin.

Caused me horrendous hunger such that i couldn't feel satisfied with any amount of food. It was terrible for me. And the side effects continue even after stopping. It was my first time in 11 years to back to hormonal contraception and l will never ever do it again. I only go non hormonal. I honestly can't take the risk.

I’ve only had the injection once and had to come off, I already suffer mental health for years and the depo made my anxiety worse, constant bloated, the bleeding never stopped which led me to constant itch down below due to wearing constant pads, my hair was falling out so so badly, now my baby hairs are growing through and I look awful, not like my self asteem is poor already,
