"i had the depo shot 3 times and for the whole 9 months i was bleeding. the first 3 months i was told it was normal and to wait another 3 months so i did. then i was told that i needed to wait another 3 months and so i did. finally i couldn&#039;t take it anymore. i was going through boxes of tampons and it had ruined my sex life with my boyfriend at that time. now i have best friend who had been on it for over 3 years and she has had no periods whatsoever! not fair right? this is not for everyone. i would recommend only giving it 3 months to see what your body does."
