"i&#039;ve been on the shot for about seven months now, and haven&#039;t experienced any of negative side effects that i&#039;d heard horror stories about (no weight gain, no unusual acne, no unusual hair growth, no significant appetite changes, etc). i did have pretty irregular spotting and bleeding for the first three months, but now i can&#039;t remember the last time i saw any blood, which suits me just fine! overall the drug has treated me pretty well - i like not having to deal with my period each month - the only downside for me is having to schedule regular dr.&#039;s appointments to get the injection."
