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.

Depo-Provera shot  

The beginning i bled a lot, 40 plus day periods with few breaks in between. After about a year my periods went away and I only have spotting now. I recently found out I should only be using this form for no more than 2 years but this is my best option. It has been affecting my bones because I experience pain in my knees and hips that I haven't before this birth control. It does control my acne and is reliable which is a plus for me, i haven't experienced weight gain which is a common side effect. I have migraines more often after my shot and leading up to it as well. Overall I don't care for birth control in general and will be looking for other options.

Depo-Provera shot  

I became depressed and experienced pregnancy symptoms. I had it for a year. Half way through that year is when I realized it was the birth control that was making me feel out of wack. I had a horrible reaction receiving last shot and that was it. I continued using it because I thought my body was suppose to get use to it. I’ve changed a lot since then and not in a positive way.

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
