birth control
"I've been taking tri-sprintec for about 5 years. It stared when I was 15, and the first few months my face had acne absolutely everywhere; the acne lasted about 3 months. 
 Some of the side effects did occur to me such as anxiety, mood swings.. but the most important fact is that I have not gotten pregnant, and the pill is easily affordable.. so that's why I keep using it."
