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.

Sayana Press injection  

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.

Noristerat injection  

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

Depo-Provera injection  

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.

Noristerat injection  

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,
