"i&#039;m getting close to the end of my second year on this birth control. i have to switch because of the bone density thing, but i&#039;ve taken calcium supplements the whole time so i don&#039;t believe my bone density was affected much if at all, but that&#039;s just speculation. i did gain a little weight in the last year, but i was also in my freshman year in college, so it may have just been my lifestyle change. after a few months on the shot, i stopped getting periods completely, not even any spotting. this may worry some people, but i got used to it. i have zero complaints for this birth control method overall."
