"so far i have been using this birth control for 1 month 2 weeks now. this is my first birth control. i&#039;m 21 and ever since my period (before birth control) i&#039;ve had bad crapping, vomiting sometimes, and nausea. also i had irregular periods that last 10 days sometimes more. now with this birth control i have regular periods (along with the help of iron pills prescribed by my obgyn) . i have no breakouts. no throwing up nothing. did have slight headaches in the first week of use but it&#039;s gone now and no babies.. (don&#039;t drink or smoke)."
