"i&#039;ve had two shots already, and so far it&#039;s been almost perfect. i actually switched to this because i&#039;m slightly underweight and i&#039;ve heard many stories about women gaining weight on the shot, so i switched in hopes that i would. so far i haven&#039;t noticed any significant weight gain, the only side effects i&#039;ve had are headaches for about the first week after getting the shot and i started getting acne on my face. i&#039;ve never had acne, so this was kind of disappointing for me. it&#039;s nice not having to remember to take a pill every day and my periods are already almost non-existent. plus my insurance covers this so the prescription is free and there&#039;s no fee when i go to get the shot!"
