"i was on the shot for a little over 3 years i gained a total of 5 pounds being on the shot.  i got off the shot because it was ruining my teeth!  it had been awhile since i went to the dentist but when i went i was told i had 17 cavities. i was shocked! i bush my teeth everyday, i may not floss like i should, but 17? that&#039;s not the worst part thought after they fixed all my teeth i go back a month later for a cleaning to find out i had gotten 7 more cavities.  how does this happen within a months time?  i finally realized it was the depo-provera after actually reading the paper the doctor gives you every time you get the shot."
