4. Insert

With one hand holding the Caya® in the folded position, open the labia with the other hand. While keeping the Caya® folded, insert the diaphragm as deeply as possible. Push down so the diaphragm slides along the posterior vaginal wall toward the tail bone. You will need to shift your hand position as the diaphragm is inserted, so eventually your finger will push on the anterior edge of the Caya® as you push it into place. The cervical cup should be covering the cervix.
