Cap or diaphragm  

I decided to invest in the Caya diaphragm since I was determined to find a non-hormonal method I could use that wouldn’t impact sex too much (I get irritation with condoms and the copper coil moved out of place pretty much immediately). I really wanted it to work but unfortunately it was way too uncomfortable during sex. It feels like there’s just way too much ‘stuff’ inside me. And I think it obstructs my natural wetness (I suspect that’s why some people mention a lot of discharge upon removal). My partner also said while he could definitely feel it, it wasn’t uncomfortable. I’d choose condoms over the diaphragm unfortunately. Hope this helps :)

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.

Noristerat injection  

took some time before i ever come here mainly because i was scared , shy , & hated myself for what im about to talk about here❤️ trust me when i say it’s hard ( im even trying not to cry ) shap so i started my pregnancy prevention journey this year on April it’s been 6 months now & never missed even a single dose (big ups!!) Starting it was so fun & games bcs i would notice some changes & that for me was a game changer bcs I’ve always wanned to gain weight so badzzzz ( i lost weight before so starting this journey for me was a bounce back ) may started eating a lot!! , June my periods desappeared July i got some pimples , august i experienced painful headaches, September my mood swings would change here & there & all that came unoticed to me because that one thing I’ve always wanned does not happen im not gaining still , bro im so drained i feel like it’s so useless for me to inject i don’t know but yeah hey i just hope god pulls through im even thinking of leaving it

Sayana Press injection  

I have had no negative side effects with Sayana Press and my periods have stopped completely, of the four different contraceptives I've tried over the years, this one is my favourite.

Depo-Provera injection  

Depo-Provera was great for me and it stopped my periods completely. I liked not having to take a pill everyday and I didn't want to get another copper coil so this worked well for me. However after being on it for quite a while I got unlucky and ended up with an abscess at the injection site which eventually had to be operated on, however this could have happened with any kind of injection and was just bad luck. I have since switched to Sayana Press so that I can do my own injections at home and clean the injection site beforehand to prevent another abscess.

Depo-Provera injection  

Worst experience I’ve ever had. Since taking this I’ve felt constantly irritated, had complete lack of concentration and it’s completely wiped out my sex drive. I have now been bleeding for 2 months with no break. I have never regretted taking something so much it’s honestly made me miserable.

I had no problems while using noristerate but I would get annoyed sometimes because I would experience spotting for 2 weeks before my next injection. I had little to no menstrual cycle.
