There are four different types of volcanoes. A volcano is categorized both by formation and appearance. Different types of volcanoes also indicate the types of expected eruptions. The different types of volcanoes are: composite (or stratovolcanoes), shield, cinder cones and spatter cones.
A Vaginal Ring is a thin, transparent, flexible ring that you insert into the vagina yourself to provide contraception protection. Leave the Vaginal Ring in for 3 weeks while it slowly releases estrogen and progestin hormones into the body.
NuvaRing (the ring) is a combined-hormone method of birth control. It releases estrogen and progestin to protect against pregnancy for one month. A woman inserts the ring deep inside her vagina. A new ring is inserted only once and left in place for three weeks in a row. At the beginning of the fourth week, itâs removed and menstruation occurs. If you havenât been on the pill, patch, or ring in the last month, start using the ring on or before day five of your menstrual cycle. (Day one is the first day of bleeding.) Pregnancy protection will begin seven days later. In the meantime, use a latex or female condom to reduce the risk of pregnancy.
