The vaginal ring prevents the ovaries from releasing an egg each month (ovulation). It also changes the lining of the uterus making it difficult for an egg to attach itself, and it changes the mucus in the cervix making it harder for sperm to enter the uterus.
Vaginal Contraceptive Ring
What is the vaginal contraceptive ring?
The vaginal contraceptive ring, also known as the NuvaRing®, is a bendy, soft, one size fits all, silicone ring. The ring is inserted in the vagina and remains in place for 3 weeks at a time. The vaginal ring contains two hormones, estrogen and progestin, which are absorbed through the walls of the vagina and then distributed in the blood. The vaginal ring does not require sizing or fitting and is 99.7 per cent effective if used the right way.
How does the vaginal ring work?
Anyone seeking a reliable and reversible method of birth control that does not require daily attention. It is important to consult a healthcare provider, as the vaginal ring should not be used if you have certain health conditions.
How do I use the vaginal ring?
The vaginal ring is made to release a steady amount of hormones over a 21-day period followed by a seven-day ring-free period. Each ring is used for one cycle and then removed and discarded.
Insert a vaginal ring into your vagina and keep it in place for three weeks in a row. Remove the vaginal ring and after seven days, insert a new ring. Your period should begin during the ring-free week. The vaginal ring should be left in place during sex and is usually not felt by either partner. It can be used with condoms and tampons.
- To insert: After washing your hands, squeeze the vaginal ring in the middle between the thumb and the index finger and insert it into the vagina as far as it will go. The exact placement is not important for the vaginal ring to work and the muscles of the vagina should keep the ring in place.
- To remove: Put a finger into the vagina and pull it out. Put the used ring in the foil pouch it came in and then in the garbage, not in the toilet.
On rare occasions, the vaginal ring can slip out. This can happen if the ring is not properly inserted, if you strain for bowel movements (stool) or sometimes during sex.
If your vaginal ring slips out, follow the instructions included in your vaginal ring package, or visit Stay on Schedule for more information.
