birth control
"My doctor prescribed me Lo Loestrin when I was 15 to treat my heavy, irregular periods and cramps that would cause me to stay home from school/other obligations for days at a time. It worked perfectly for me for the 5+ years that I used it! My periods lightened and became extremely regular, and it worked as pregnancy prevention later as well. I didn't experience any abnormal weight gain, and it didn't affect my acne whatsoever (neither lightened it nor made it heavier). I would definitely recommend LLF!"
