"i had the implanon put in 6 months after having my son in 09. it didn&#039;t hurt when they put it in just a little sore. after that i let my body get adjusted to it but on down the line my periods were light and only last 3-7 days and i go a whole month without having a period. the only bad part about the birth control is that i have very bad mood swings, and my acne comes and goes and i have gained weight and i go to the gym every night but no changes// uggggh."
