Natural Cycles App  

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!!

Symptothermal method  

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.

Kyleena coil  

for me it works great, but i have a feeling my sex drive changed plus also the intensity of my orgasm. But you know I cannot tell for sure that the coil is the causing this..

Kyleena coil  

Positive - first one for 5 years, protected against pregnancy, stopped periods after about 18 months so saved money on tampons. No significant side effects initially. Set and forget method was great. Negatives - I found the fitting incredibly painful. When I had it changed after 5 years the reinsertion was traumatic and I won't have it again. I suffered with mouth ulcers every month that got progressively worse over time. My mood wasn't bad but it was overall flattened. The new one never settled and I had problems with the threads travelling upwards, I found medical staff across the board (GP, clinic, hospital for ultrasound) very uninterested when I had issues after fitting which was difficult because I was frightened of possible consequences if it moved or they couldn't get the threads to remove it. I have honestly never had thrush so much in my life as I did when I was on kyleena. Noticed more and darker body hair over time.

Mirena coil  

Works well for me, was hoping would take away periods altogether but definitely made them lighter. Found fitting comfortable as just had some cramping. But I have quite a low cervix, so I could feel the strings and needed them trimmed.

Mirena coil  

Not pleasant to put in but completely stopped by periods after few months. Reassuring that no pregnancy, however absolutely 0 sex drive and this effects relationships.

Mirena coil  

Initial 3 month settling in period is intense, lots of bleeding and emotional side effects plus insertion pain. After 3 months it settled and I thought I had found the holy grail, emotionally stable and no side effects. At 6 months I developed a large ovarian cyst which put me in agony and A&E, doctors said this was caused by the coil and had to remove it. Unfortunately I cant recommend, the search continues.

Mirena coil  

Prior to having the mirena coil I had the most horrific periods literally to the point of passing out. I can say I have had my coil in for nearly 6 years and not had a period since and now I feel like I have my life back! It has been one of the decisions I have ever made and also hardly had any hormonal side effects.

Mirena coil  

I loved the mirena but over 3 different coils, shortly after insertion I would get kidney infections that didn’t respond to antibiotics. The link was only made on the third despite me asking the gyno about it. Such a shame because I loved it otherwise. Kidney infections mostly skipped the uti stage and went straight to them but bacteria wouldn’t grow in pee. If this sounds like you remove it!

Levosert coil  

Had it inserted at birth during a c section so no pain for insertion. Periods for lighter every month with significantly less pain than before and have virtually stopped after 8 months - just a small amount of spotting.
