Well yeah, if you get a Depo Provera shot every 3 months you will prob lose yer period...a lot of people do...periods are stupid...i havent had one since i was 13. fine with me. i noticed that when it went away, i did feel even more masculine than before. i got the shot in the 1st place to eliminate the period, which i was grossed out by and didnt feel natural to me at all. It's not healthy to be on it for more than a few years, and def not for someone so young, cause loss of bone marrow density as well, not so good...only found this out when i got the shot in Cali, they dont tell you most places...anyway i have no money, so no other option....
