English: The vaginal ring contains oestrogen and progestogen, which prevents ovulation and minimises the risk of an unwanted pregnancy. The vaginal ring has lower hormone levels than, for example, birth control pills. The ring is thin and about 2 inches (5 cm) in diameter and is made out of plastic. To make the ring fit into the vagina, it has to be folded and put in like a tampon. The vaginal ring is left in the vagina for three weeks and then taken out for a week, which is when you get your period. When your period is over, a new ring is put back in.
