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.

Symptothermal method  

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.

Natural Cycles App  

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.

Cap or diaphragm  

I’ve enjoyed using the cap around my fertile window but struggle to feel 100% confident I have inserted it correctly. When removing the cap I notice a lot of discharge but not after use, only when removing. Way better than the pill or condoms for me.

Cap or diaphragm  

Apart from the issue I'm currently dealing with (it getting stuck inside of me), I LOVE the diaphragm. I found out I wasn't never fitted (which is why it kept getting stuck upon removal), so my new, awesome doctor actually sized me. It's easier than popping in a tampon once you learn how to do it and then ya pop it out the morning after sex. No side effects, no hormones, no emotional hangover. It's very hard to find though. Pharmaceutical companies don't want women to buy one silicone object that lasts for the rest of your life, so finding the right size and actually getting it has been a challenge. My mom used it and only got pregnant to have me (her only child) and I've been using it for 5+ years with no issues.

Cap or diaphragm  

I've used Caya several times over the past couple years (they last up to 2 years- due for a new one now). I use it on the edges of my fertile window (with fertility awareness) and/or combined with withdrawal or condoms to boost efficacy during the fertile window. Always use with Caya/Contragel- they come with an applicator to re-insert the gel into the vagina, as you need to reapply the gel each time you have sex. Watching the YouTube instructions on how to put it in (plus the instruction manual in the box!) helped me understand how to use it properly and to have an idea of how it was inserted properly.

Cap or diaphragm  

I used the caya cap. It has been a game changer after previously taking the pill. I feel in control, no need to remember to take a pill, just put it in when needed. Better than condoms as it is women based and not detectable. Effect of not taking hormonal contraceptives has been amazing. All the side effects that I had ( migraines, reduced sex drive, dryness, breast tenderness, strong period pains, breakthrough bleeding and emotionalness) all gone. I wish someone had told me about it before!

Cap or diaphragm  

Having experienced terrible physical and mental health side effects from both types of contraceptive pill (Combined and POP), and permanent pain and repeated UTIs with the copper coil, I hoped that Caya diaphragm would be a suitable non-hormonal method to try. Unfortunately, I found insertion very tricky - it seems I have a case of "deep vagina, small fingers", as I could never tell whether I'd pushed the diaphragm up far enough to cover my cervix, and sex was always a bit uncomfortable. I'm naturally prone to cystitis and thrush, and getting both while using the diaphragm also put me off using it long term. However, on the plus side - I didn't get pregnant (though I was still breastfeeding a lot, and my periods hadn't yet returned postpartum), and I did manage to avoid the hormonal depression, skin changes and weight gain/loss that I've experienced in the past with pills.

Cap or diaphragm  

Fiddly and a faff. Didn’t bother a couple of times and ended up pregnant. He’s nearly 20 now and I’m still married to his father so not all bad :) Tried the copper coil for a bit after but it gave me very heavy periods and stomach cramps which had never been a problem before. Switched to the mirena coil and now on my third - no periods for 15 years and no menopausal symptoms despite being 52. What’s not to like?

I was only using it shortly, as I wanted to avoid hormones. It was not bad, but the need of using a spermicide as well was the reason why I stopped, I had vaginal discharge caused by the spermicide.
