Diaphragm

A diaphragm (like a cap) is a barrier method of contraception. It fits inside your vagina and prevents sperm from passing through the cervix. To be effective in preventing pregnancy, diaphragms need to be used in combination with spermicide, which is a chemical that kills sperm. You only have to use a diaphragm when you have sex, but you must leave it in for at least six hours after the last time you had sex. You can leave it in for longer than this, but do not take it out before.
You only need to use a diaphragm when you want to have sex. Also you can put it in at a convenient time before having sex - but do not forget to use extra spermicide if you have it in for more than three hour.
Diaphragm provides limited protection against sexually transmitted infections (STI's) and it can take time to learn how to use it. Putting it in can interrupt sex and it is not as effective as other types of contraception - 92-96%.
Most women are able to use a diaphragm. But if you have a high risk of getting a sexually transmitted infection (STI), for example, if you have multiple sexual partners, if you have weakened vaginal muscles or you have a sensitivity or an allergy to latex or the chemicals in spermicide this method isn't good for you.
