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.
You put the ring into your vagina and wear it for 3 weeks in a row. You take it out in the 4th week; thatâs usually when you get your period. But you can stop your period if you wear it for three week, take it out, and put in a new one.
