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

Nexplanon implant  

I have had the implant inserted 3 times. First 2 times barely had a period here and there. Always had one for a little longer right after it was placed. But the last time over a year ago it was fine until the last 4 months. I have had a period about every 2 weeks. Starts stops, starts stops. Not sure why but super annoying. Better than the pill and having a pregnancy. My kids are grown. My period has always been 28 days like clockwork. Wish I could not have the sporadic spotting but what do we do??🤪.

I’ve been on this for 2.5 years, my periods average 17-28 days, heavy flow, and cramps that leave me throwing up and laying on the ground. My vaginal dryness was horrible, I feel so bad for my partner because we have to stop for more lube.

I’ve lost my sex drive almost completely. I don’t enjoy sex anymore it feels like a chore. My weight has fluctuated 15lbs while on Nexplanon. Vaginal dryness has also been a problem due to my sex drive not being there.

Nexplanon implant  

When I first started this birth control, I had a period for three months on and than it stopped for three months and that cycle continues into my second year where my periods got more regular like normal. Now in my 4-5 year of use and getting a fresh implant i do not get a period at all. I also noticed a significant amount of weight gain when i started on it about 35 lbs.

Nexplanon implant  

Nexplanon was effective as far as preventing pregnancy. However it has caused sharp pains in my head and heart, increased pulse, high blood pressure. Anxiety, depression, hopelessness. Swelling in my legs up to my knees. Huge weight gain and difficulty loosing weight. It has slipped and hasn’t been found. Sleepless nights, due to increased heart beat at night. An adrenaline attack only at night.

Nexplanon implant  

I got on the birth control on the same day I had a surgical abortion due to abnormal ultrasound 14 weeks into pregnancy in 2019. My body was going through a lot of hormonal changes as expected. Severe bleeding for several weeks occurred yet once my body adjusted to the birth control, I have not had any issues. Lighter regular periods with no side effects or unexpected pregnancies. I kept the first implant 5 years to the date of insertion and had a new one inserted in 2024. No heavy bleeding, side effects, or changes occurred. Highly recommended for those who wish to avoid pregnancy until the time is right and do not want the responsibility of taking the pill daily. Give patience to the implant as it may be slightly overwhelming at first but rest assured I have had absolutely no problems, pains, or poor side effects!
