Copper IUD ingredients

Copper coils are made of a T-shaped frame of polyethylene (plastic) and barium sulphate. Copper wire is wound around the vertical arm.

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.

Copper IUD  
Used for 5 - 8 yr

  •  2 weeks ago

Paragard IUD  

I had Paraguard for almost 7 years. When it was first inserted (insanely painful) I was told it would last for 12 years, however it fell out recently. Only half fell out, as one arm broke off and I was recommended to have a hysteroscopy under full anesthesia to remove the missing part. Luckily it came out on its own and I didn’t require the operation but it was a terrifying experience. Throughout the past 7 years the only issues I had was very heavy periods and severe cramps (including sharp pain when going to the bathroom). Other than that, it was great for me and nice to have regular periods.

Paragard IUD  

I've never used any forms of birth control before, so I don't know what to compare it to other than being normal and not on birth control. Insertion was uncomfortable but not very painful, and I had pain in my cervix and spotting for about a week afterward. My body adjusted very quickly and I had normally spaced periods right after. The most noticeable difference is that my period is lighter and longer. My sex drive noticeably decreased, and my emotions are dampened/numbed. I forget that I even have it 99% of the time, as I don't notice it in my daily life. If all you're looking for is plain and simple low-maintenance birth control, this is it.

Paragard IUD  

Cramping is significantly worse than before I had the IUD. Periods have lasted about 3 weeks when they used to only last 5-7 days. After the IUD was inserted, I ended up having 3 UTIs and cervicitis.

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
