"i&#039;ve been on this pill for almost a year now, and this is the only birth control i have ever been on. my period is erratic, and has been 4 days late before. i have insane cravings, and went from having regular light easy periods to long painful ones. the second month out of the three month pack is always the better month, but i am certainly switching. also lost about 10 pounds, and nothing i&#039;ve tried works to gain it back. every body is different though! good luck on your birth control quest!"
