For added protection, insert extra spermicidal jelly or cream with an applicator into the vagina with the diaphragm in place. At the time of ovulation you may want to use an extra applicator full of spermicidal jelly or cream or use a condom wi th the diaphragm. You must leave the diaphragm in for at least 6 to 8 hours after intercourse. If you have intercourse a second time, leave the diaphragm in place and insert another applicator full of spermicidal jelly or cream into the vagina. It is not necessary to remove the diaphragm promptly after 6 to 8 hours.
Some women prefer to leave it in place until the next morning or until convenient.
In any case, don't remove the diaphragm until at least 6 to 8 hours after the last inte rcourse. It should not be left in place for more than 24 hours. To remove the diaphragm, insert the index finger behind the front rim of the diaphragm and pull it out gently, following the direction of the floor of the vagina. Sometimes it is helpful to use the index finger and the thumb. Bearing down ge ntly will aid in its removal.
