How do I know a diaphragm is in correctly?

When inserting a diaphragm, get comfy and start with it facing up, like a little bowl full of spermicide. Pinch the sides together and push it as far up and back into your vagina as you can, then use your fingers to make sure it covers your cervix. If it’s uncomfortable, the diaphragm may be the wrong size or not inserted quite right.

Still not working?

If you aren’t sure your diaphragm is in correctly, try going to see a health care provider in person to check the fit. In the meantime, consider using another method of birth control to prevent pregnancy, like condoms.
