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 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

Mirena IUD  

My first IUD placement (Mirena) was without numbing shots, and it really was quite painful. The immediate pain lasted only a few seconds, but I had hot flashes for a few minutes afterwards. The next week, I got the heaviest period of my life, followed by about 4 months of light bleeding. After that, I lost my period completely for about 3 years, and then very light and irregular periods until I had it replaced. My period used to cause painful acne and very frustrating mood swings, which I was quite happy to go without. I did have some discomfort during sex, but only with larger partners and only in certain positions. My second IUD was the Kyleena. I did have numbing shots for the placement, and it was much more comfortable - similar to getting a pap smear. My period has gone away again, and I haven't noticed any pain during sex (Kyleena is a little smaller). My only real concern about the IUD is that if I were to become pregnant while the IUD is in place, it is very likely to be ectopic. I do take a pregnancy test every couple of months, so if it does happen I can get the care I need. I live in a state with very good and safe abortion care, so I would be able to get help right away, but it's still something to keep in mind. All that being said, I would 100% recommend an IUD. I have been nearly period-free since 2018, which is well worth the pain of insertion. I really appreciate being able to avoid the acne, pain, and mood swings I used to get with my period, and I really really appreciate that I have an incredibly effective form of birth control that I only have to think about once every 8 years. I love my IUD so much, and I am probably going to use IUDs as my primary form of birth control for the rest of my life.

Mirena IUD  

If you are considering the hormonal IUD route, I highly encourage you to read this! I primarily chose to switch over to the Mirena due to the weight gain I experienced while on the pill. To preface, I never had any issues with vaginal dryness prior to the switch. Following the insertion, I have been almost completely unable to get wet. As I stated before, this was never a problem for me regardless of arousal. It has been over a year, and without using an external lubricant, I physically cannot have sex due to the severity of this issue. It can be humiliating if the person i’m getting with isn’t aware of the causation. Just wanted to make it known, because it’s impacted my life pretty significantly.

Mirena IUD  

I took this for endometriosis and it dialed my pain and symptoms down from a 9 to a 2-3, for a whole year. Unfortunately after a year I felt the pain begin to creep back in, a little more intense every month after that year mark, so I decided to pursue excision surgery as a more permanent solution. If you’re not ready for surgery but want endo relief, definitely encourage you to give Mirena a try!

Hormonal IUD  

Caused increased anxiety, extreme cystic acne that did not respond to prescription acne treatments, and severe hair loss. Made my periods longer and heavier at first, then they finally started getting lighter but I was still spotting almost every day. Gave me hot flashes badly.

Kyleena IUD  

Didn't use it long enough to really form an opinion yet, but the reason I got it in the first place was because of very heavy periods and cramps. It has helped with that.
