"i&rsquo;ve been taking mononessa for a month and a half, since day one i noticed a slight headache i didn&rsquo;t pay much attention to it since i thought it was just balancing my hormones. the following weeks went by and my headache got worse by the time my period came i experienced cramps very bad cramps making me cry (30 year old crying worst period ever) i called my doctor and told her my symptoms she told me that it was normal that eventually my body would get use to the medication. once again i&rsquo;m on month two second week i&rsquo;ve been experiencing terrible heart burn, diarrhea, vomiting &amp; extreme headache so i threw them away. if your taking this pill i hope it works for you it didn&rsquo;t for me :("
