"i tried it once my sophomore year in high school. i bled the entire time and tried to commit suicide. it made me crazy. i had many mental breakdowns. i got back on the pill for a year then got back on the shot because i can&#039;t remember to take any meds. this time around was better, but i have gained weight i can&#039;t get rid of. i don&#039;t get a period and because of that i always have yeast infections. it&#039;s effecrive, but many of the women i know say their ovaries went into &quot;hibernation.&quot; do not try it."
