"this is horrible. i switch from another birth control to hopefully fix my arousal issues. i&#039;ve been on it for 2 months and my period 80% of the time. i&#039;ll have my period for 9 days then no period 3-4 days and then have my period for 9 days again. it&#039;s been aweful. i also have horrible cramps now and i never use to have them. not to mention it&#039;s not helping with me and my partner having sex more because i&#039;m constantly riding the crimson wave"
