The ring cannot be incorrectly inserted. Its exact position in the vagina is not critical for it to work because the ring is not a barrier contraceptive. The ring is left in place during sexual intercourse. It is replaced with a new one every 4 weeks.
Note the day that you insert a new vaginal ring. Leave the ring in place for 3 weeks.
To take a 1-week break to have a menstrual period, remove the ring on the same day of the week that you inserted the ring 3 weeks before.
Insert a new ring on the same day of the week as you did 4 weeks ago.
If you forget and leave the ring in place for more than 4 weeks, remove it and use a barrier method of birth control (such as a condom) until a new ring has been in place for 7 days. Discuss this with your doctor. A pregnancy test may be recommended.
Insertion and removal of the ring is similar to using a diaphragm, except the ring is left in place for 3 weeks. Simply use your fingers to tuck it into your vagina and later to hook or grasp it and pull it out.
