How do I know a diaphragm is in correctly?

When inserting a diaphragm, push it as far up and back into your vagina as you can, and make sure to cover your cervix. You’ll know the diaphragm is in correctly if you can’t feel it. If it’s uncomfortable, the diaphragm may be the wrong size, or not inserted quite right.
