"i started on this a while ago. it was wonderful actually i never had problems getting my period on time, it always works and my cramps weren&#039;t bothering me. i moved and my pharmacy gave me levora- same amount of active hormones but, levora gave me god awful cramps all times of the month, made me miss my period for a month at a time, get 2 periods a month and sometimes just get it in the middle of the cycle. marlissa doesn&#039;t give me that issue at all- i am so happy to be back on it again! there&#039;s a reason why there are so many types and brands, everyone&#039;s body will respond completely different"
