"i&#039;ve been on lutera for about 4 years now and its been pretty good! no huge complaints at all here! my breasts definitely got bigger but besides that not much weight gain as others have mentioned. i do have mood swings ever since i started lutera but i mostly just cry easier when i&#039;m pmsing and that&#039;s it. as for effectiveness it works great and i pretty much have my period down to the hour at which i know it will start. if you take the pill as instructed, it works great!"
