Hi everyone! I’ve been using Natural Cycles for a while now and it’s genuinely helped me feel more in control of my cycle and fertility awareness. If anyone here is thinking about trying it, I have a referral code that gives you a discount on subscription (and also helps me get closer to becoming a Star Cycler). If you’d like to use it, here it is: https://www.naturalcycles.com/refer-a-friend?name=QmV0aA%3D%3D&code=referralid20&referral=70eqzvinl2i98q15&utm_source=NCApp&utm_medium=inappbutton&utm_campaign=refer_a_friend_page No pressure at all — just sharing in case it helps someone save a bit while getting started. Happy to answer questions about my experience if that’s useful too 😊 With this you get a free thermometer and a 20% off :)

I used natural cycles to prevent and plan pregnancy- worked fabulously on both occasions. After my daughter was born I wanted a more solid contraception (sleep does impact your basal temp guys, so with a newborn, not the one)- now she sleeps through I will be going back!!

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've had the mirena coil for four months, I'm still bleeding irregularly (period every 8 days) and lots of spotting. I've been dizzy for months, I'm feeling very low, I have water retention and a lot of lower back pain that feels like a pinched nerve so I'm battling to concentrate on work. I really want to have it removed but I'm terrified of going back to the alternative of extreme heavy periods that made me anemic.

I had Kyleena for 5 years. For the first 6 months I had painful cramps, but my cycle became very light. I have noticed that I have had increasingly more acne, especially back acne, so be prepared for your skin to be very itchy. Towards the end of having it, I had constant light bleeding through the month and there was no regularity to it (probably because the hormones were wearing off). I have had incredibly bad bloating, water retention, and generic weight gain. I'm a very light build so this weight would normally have been easy to lose. Finally, I had to undergo investigations for ovarian cysts as I was getting all the symptoms for them, and after a bit of research it turns out that Kyleena can be a contributor to the formation of cysts. Overall, I have really liked the Kyleena. The side effects have been fairly insignificant compared to other methods. But just take into account the potential insidious side effects like cysts etc that can happen. I've now switched over to the copper IUD because of these side effects, and I'd prefer to be hormone free.

I've had great success with a Mirena for treating jawline acne, after getting it to prep for going onto Roaccutane it actually cleared my acne up amazingly and now I just get the odd spot every month when I'm due on. I get irregular, yet light periods, and occasionally some spotting, and overall my period cramps have been lessened. My sex drive is not what it is when off hormonal contraception, but as I've been on hormonal contraception my whole adult life, bar a couple of years here and there, this hasn't been an issue overall. I have put weight on gradually, but I've also aged (now 34), so its more likely to be metabolic changes rather than a side effect. The only thing I would say is that the coil itself has moved twice, resulting in removal and replacement (I'm waiting for another removal, and will likely explore pill options again as its just too painful getting it replaced every 2 years!). It should last 8 years, but for whatever reason, maybe my anatomy, mine moves to be too low, and then the long process of getting it checked, ultrasounds, appt waiting times for removal, and everything else, means its not something I want to continue using at the moment. Overall though, it has been a really good method for me, and just because mine hasn't stayed where it should be, doesn't mean someone else won't have a good experience, its probably down to my anatomy only!

I was very worried about trying this method as I’d not used hormonal contraception before but overall it has been positive. The insertion was quite painful but not unbearable. It took about a week for me to recover, with me having to stop exercise for that time and then slowly increase again. Bleeding has been the most annoying part as my periods are very irregular now (previously they were regular as clockwork) and I have light spotting for up to a week before each period. But it’s getting slightly better each month and I’m hoping I’ll be one of the lucky ones who eventually gets to little or no bleeding at all. I’ve suffered no other symptoms of note.

I've had the hormonal mirena for 14 months now to reduce endometriosis symptoms. My periods have reduced in length (used to be 3 weeks) and happen irregularly and the pain has settled during these. I have however noticed continuous weight gain since I went on it, despite very little changing in my diet and exercise. I've always stayed at a very stable weight and now my breast have nearly doubled in size and my weight in general continues to creep up. I have tried upping my exercise with no improvement in my weight. I'm the heaviest I've ever been, except for pregnancy. It's a huge price to pay for a reduction in endo symptoms. It's very frustrating.

The insertion process wasn’t pleasant and I found very painful however I will say it was very quick and the pain didn’t last. After leaving the doctors I felt fine apart from a little light headed but that was due to me stressing. The next day if I didn’t know if had it fitted I would be none the wiser as I felt normal and had no issues. Since then I have really liked not having to think about it, I had no periods at all but have started to get a day or so of spotting once a month at the 18 month mark and some light cramps. The only other negative to me is that it’s meant that I now always have to use lube for sex as it’s definitely affected dryness. The best overall contraception I have tried

Such a hideous experience for me I went to the doctors to get it taken out ASAP. Had severe mental health dip and felt suicidal which was really unlike me. The pain on inspiration was absolutely awful (removal was easy and painless).

Random cramps throughout the day, they suddenly stop and start again a few days later. Period almost completely gone, but random spotting through ovulation and calculated period days (on clue app). Very bad breast tenderness during ovulation and periods

I’ve had the mirena in for almost 2 years and it’s been working great as a contraception and minimal side effects (very light periods).

I'm on my second Jaydess (been using it for almost 6 years now), before I was on the pill (estrogen+progesterone combination) for about 6 years. Insertion is no fun for me, other than that I can only recommend it. Compared to the pill I have much lighter periods, period pain has significantly decreased (I get a little abdominal discomfort+back pain a day before the start of my period, and that's it). Acne stayed about the same as on the pill. I get a little breast swelling/tenderness for about one week every cycle which I think has slightly increased compared to the pill but isn't so bad. Sex drive and mood stayed about the same, if anything, my mood has become more stable on Jaydess actually (but that could also be attributed to me growing up I guess). Overall I'm satisfied with it
