"i was switched to this after about 9 months of mononessa. i didn&#039;t ask to switch it just happened. anyways, i did not experience any side effects at all. my only small complaint is that my period doesn&#039;t start until mid-late wednesday and it&#039;s just inconvenient because on mononessa it start monday night or tuesday morning so i freak out a little bit over that. i do think it made my cramps less intense and my period lighter. it still lasts about 6 days although the last two days are almost nothing. i was afraid to switch but it wasn&#039;t bad so if you&#039;re in my shoes, think positively!"
