"i used to use depo-provera for about 8 years.  i have two girls 13 and 7.  i decided to change to mirena with our busy schedule so that i don&#039;t have to keep coming in every 3 months for a shot.  the first 24 hours of cramping was not pleasant.  but as with depo-provera i have continued to not have a period and no weight gain for me.  i strongly recommend for anyone with a busy family life who wants good birth control, if you didn&#039;t get your tubes tied."
