"took this for 1 month and experienced no major mood swings or nausea.  however, immediately, i got canker sores (i never get these) and pimples (when my complexion is generally clear).  then i had light spotting for a few days about 1.5 weeks prior to when my period should have came - then it was followed by heavy breakthrough bleeding.  can&#039;t recommend this if you&#039;re trying to regulate your period.  will be switching to a different brand."
