A diaphragm is a shallow, dome-shaped cup made of latex or silicone. You insert the diaphragm into your vagina, and it covers your cervix to keep sperm out of your uterus. One super important thing to remember: For a diaphragm to work effectively, you need to use it with spermicide.
Comfortable with your body.
If you’re not okay with putting fingers inside yourself, a diaphragm probably isn’t for you. To be sure you know how to use your diaphragm, you can practice putting it in and taking it out while in your health care provider’s office. Your health care provider will check to make sure the diaphragm fits right.
It takes discipline.
You have to remember to insert your diaphragm each and every time you have sex, so it takes a bit of self-discipline and planning. You’ll have to carry it with you if you want to be prepared anytime.
If you’re allergic to silicone or spermicide, you shouldn’t use a diaphragm.
Not while you’re bleeding.
Don’t use a diaphragm while you’re having your period.
The pregnancy question.
You’ll be able to get pregnant as soon as you stop using the diaphragm. So protect yourself with another method if you don’t use it.
How to Use it
A diaphragm can be inserted just before sex, but it can also go in hours before that so it doesn’t get in the way of the moment. But no matter when it goes in, you have to be sure to leave it in for at least six hours after you have sex. If you’re going to have sex again that day, just leave the diaphragm in place and insert more spermicide way up in your vagina. But don’t leave your diaphragm in for more than 24 hours, either.
Before you put it in
Add about a teaspoon of spermicide to the inner part of the diaphragm and spread a little of it around the rim as well—but not too much, or it’ll be too slippery to hang on to! The spermicide Ortho Gynol II is specifically designed for diaphragms, and it comes with an applicator you can use if you’re going to have sex more than once within six hours, as you’ll need additional spermicide. Any kind of contraceptive gel or spermicide will do, however, except for film or insert/suppository types. Don’t forget to check the expiration date of the spermicide!
How to put it in
- Wash your hands. Soap and water, no shortcuts.
- Check your diaphragm for holes and weak spots. Filling it with water is a good way to check. If it leaks, you have a hole, which sort of defeats the whole purpose.
- Put a tablespoon or so of spermicide in the cup and spread some around the rim, too.
- Get comfy, like you’re going to put in a tampon.
- Separate the outer lips of your vagina with one hand, and use the other hand to pinch the rim of the diaphragm and fold it in half.
- Put your index finger in the middle of the fold to get a good, firm grip. You’ll be touching the spermicide, but that’s fine.
- Push the diaphragm as far up and back into your vagina as you can, and make sure to cover your cervix, which feels like the tip of your nose.
Having another go at it?
You need to leave the diaphragm in for six hours after sex. If you have sex a second time within those six hours, first insert more spermicide. Ortho Gynol II comes with an applicator that measures how much you’ll need, and it gets it where it needs to go. Then the six-hour clock starts again, counting from the last time you had sex.
How to take it out
Of course, what goes in must come out. Here’s how:
- Wash your hands again.
- Put your index finger inside your vagina and hook it over the top of the diaphragm’s rim.
- Pull the diaphragm down and out.
Care + keeping
If you take good care of your diaphragm, it can last for several years.
- After you take it out, wash it with mild soap and warm water.
- Let it air dry.
- Don’t use powders or oil-based lubricants like Vaseline, petroleum jelly, baby oil or cold cream on your diaphragm.
Inserting a diaphragm may sound difficult, but with a bit of practice, it’s not so tough.
Still having trouble?
Ask your health provider about getting an inserter, or consider switching to another method.
Thanks to the Affordable Care Act, if you have health insurance, chances are good you’ll be able to get this birth control method with no out-of-pocket cost. Tricare, the military insurance, covers this method at Tricare-authorized providers. Medicaid also covers it.
With proper care, and if you don’t gain or lose more than 10–15 pounds, you can keep your diaphragm for up to 10 years, making it the best birth control value for your buck at the equivalent of 42 cents to $2.08 a month plus the cost of spermicide.
Where to get it
See a health care provider for the initial fitting to determine the right size.
You may still need condoms
A diaphragm provides no protection against STIs, and the required spermicide can actually make you more susceptible to them.
