The ring continually releases oestrogen and progestogen, which are synthetic versions of the hormones that are naturally released by the ovaries. This: reduces ovulation (the release of an egg), thickens vaginal mucus, which makes it more difficult for sperm to get through, thins the lining of the womb so that an egg is less likely to implant there.
Advantages of the vaginal ring include: it's easy to put in and remove, you don't have to think about it every day or each time you have sex, period-type bleeding usually becomes lighter, more regular and less painful, you don't have to think about it every day or each time you have sex.
Disadvantages of the vaginal ring include: it may not be suitable for you if you don't feel comfortable inserting or removing it from your vagina, spotting and bleeding while the ring is in your vagina can occur in the first few months, it may cause temporary side effects, such as increased vaginal discharge, headaches, nausea, breast tenderness and mood changes.
Some women cannot use the vaginal ring. It's not good for you if you are overweight or you have family history of blood clots.
