"the first few weeks after my first shot were great. i didn&#039;t have any side effects. my period came two weeks late the first month and after that all hell broke loose. my period lasted ten days and ever since o have had a brown discharge. it hasn&#039;t stopped in two months. i also have horrible mood swings now. i haven&#039;t gained weight and not having to take a pill everyday is really convenient, but overall it isn&#039;t worth it."
