Cap or diaphragm ingredients

A birth control diaphragm or cap is a reusable barrier method of birth control that is inserted into the vagina before sex. It is covered in spermicide (a gel that kills sperm) and prevents pregnancy by covering the cervix so sperm can’t get into the womb. There are a few things that can make the diaphragm or cap less effective. These include if it doesn't fit properly
you remove it too early
it is damaged
you forget to use spermicide
or it is used with other oil-based products. If these things happen you may need to use emergency birth control.

FemCap  

I’ve been using the FemCap for years now and honestly, I’m so impressed. It’s non-hormonal, super discreet, and once you get the hang of insertion, it’s incredibly easy to use. Highly recommend it to anyone looking for a hormone-free option.

FemCap  

I had to come off hormonal contraception due to health reasons so needed a barrier method. It was quite awkward to insert and always had to keep checking it in case it dislodged itself, was sometimes painful or uncomfortable, my partner could feel it. I was also using an approved spermicide with it but still became pregnant within a month of use.

Caya  

My very favorite thing about the Caya is that there really are no side effects. I am not putting anything into my body that is changing the way my body functions- I put it in, leave it in a while, and then I remove it. No hormones, nothing! I’ve been advised that while the Caya can be 80+% effective when used correctly, it’s best to use it with spermicide and condoms. It is tricky to insert the first few times but super easy to remove and I quickly got the hang of a quick and easy insertion! I did find it really difficult to find a pharmacy that sold the Caya (I guess they aren’t as popular now)- but all in all, it’s been fantastic so far! I love that my body gets to function as it normally would but that the Caya helps prevent pregnancy

Kyleena IUD  

No major changes but i started to have ovarian hemorrhagic cyst 3 times in the last 3 years. Got scared and now i am focusing on family planning technique, specifically measuring Basal Body Temperature (BBT). So super excited with this. Also using this amazing app called Cosia where I am not only tracking but also getting practical lifestyle tips to make my hormonal balance settle.

Mirena IUD  

Absolutely loved my Mirena IUDs (I've had 3) compared to the other forms of birth control I've used. I did develop irritable bowel and didn't realize it was because of the IUD until I removed it and it went away (my doctor's also never suspected the IUD so I spent a lot of money and time with specialists only to find out it's a listed side effect in the insert). I've also had a steep decrease in migraines since removing my IUD, but besides the migraines and IBS, it was great!

Side affects can change as time passes. I noticed more side effects the longer I was on it.

Better than copper IUD. Similar in side effects to birth control ring except less effect on sex drive.

Kyleena IUD  

I initially thought I was having a positve experience, but after 3 months was diagnosed with Sebohrreic Dermatitis with an extremely itchy scalp and bumps on jawline. Within 5 months I started having noticeable hair loss. I have lost at least 50% density. It is now 11 months from insertion and still shedding drastically. 8 months after insertion, I started having cystic acne which Ive never experienced before. I use to have the Paraguard IUD and didnt have these symptoms

Mirena IUD  

I’ve had the Mirena since 2022 and just got it taken out today. I will preface this with I do not do well with birth control in general and it’s a struggle. I did not realize the correlation between my Mirena and my side affects. I feel like my side affects got gradually worse. I already suffer from anxiety and depression but since the Mirena was put in I have had to add on another anxiety and depression medication. I’ve also had to get on an acne medication from the dermatologist because I was getting deep acne and my face chemistry had changed including a little more facial hair growth. Once on the medication I no longer had an issue the the hair growth or acne. Let me also point out that I’ve never had acne my entire life so this was new. Everyone’s body reacts differently to birth control. I just want to make sure that I said these things in case there is another person who thought they were going crazy. I had extreme exhaustion and this increased my depression and made things much worse. I am not the only one who has had these symptoms either so take comfort in knowing you are not alone.

It's ok. No unplanned pregnancy but my periods last for 2-3 weeks and I gained 25lbs in 2 years with no changes to eating habits.
