"tri-sprintec was my first birth control. i&#039;m 15 and i&#039;d never had a regular period until this contraceptive. i haven&#039;t had any side effects except for breast sensitivity but even that hasn&#039;t been severe. my periods are also shorter, they used to be 6-7 days but now they are 4. i definitely love this birth control and will be sticking to it for a while."
