Depo good x 3months: Depoprovera is usually good for 3 months from the time of the injection. It is limited by body weight and last aa shorter period of time in very obese individuals. After 3 months (90 to 100 days) all bets for contraception are "off" and you need to do a pregnancy test since your last injection is more than one month overdue.
