How do you use a diaphragm?
A diaphragm has to be inserted high into your vagina, so that it covers your cervix. They are flexible enough to be folded up and easily inserted. The top end of the dome fits behind your cervix, and the bottom should be positioned behind your pubic bone. Neither you or your partner should be able to feel it while you’re having sex.
Before you insert it, you have to add spermicidal gel or cream to stop any sperm from getting around the edges of the diaphragm. Without spermicide, a diaphragm is much less effective in preventing pregnancy.
After you’ve had sex you must leave your diaphragm in place for at least six hours. You can then remove it easily by just hooking the tip of your finger around it.
If you decide to have a diaphragm fitted, you’ll need to make an appointment with your doctor or sexual health clinic, who will make sure you use the right shape and size diaphragm. A doctor or nurse will examine you before fitting the diaphragm, and will also give you advice about how to insert it and remove it.
