birth control
"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'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't get your tubes tied."
