"well i got the implant 7 months ago and the first month i bleed heavy but i haven&#039;t got my period again instill a couple days ago. that&#039;s 6 months without a period. i do know this is very effective since my sister, ex roommate, and friends have it and haven&#039;t gotten pregnant. considering me and my long term boyfriend don&#039;t use protection that&#039;s amazing. it effects everyone different i&#039;ve never gotten a lot of acne and still dont. i haven&#039;t gained more than a couple pounds but i&#039;m lazy so it could be anything. no side effects so far, i love it"
