"i have been on depo-provera for 11 or 12 years and love it. i started out with very few periods and all of them were very light.  now i normally will lightly spot or clot before my next shot is due. now i never have any periods so it&#039;s been great. the only problem i&#039;ve had is just recently, for my last shot i went to a different doctor and they gave me the generic version which caused me to bleed very heavily and severe cramping so i know to never use the generic form again."
