What does Depo do to your body?

The birth control shot. The birth control shot, Depo-Provera, is a hormonal injection that prevents unplanned pregnancy for three months at a time. The hormone in this shot is progestin. If you have your shot on time without being late, there's a 1 in 100 chance you'll become pregnant during a given year.
  • Can the Depo shot cause long periods?

    "Depo Provera can cause prolonged spotting (bleeding is usually light and not like a period), especially after the initial administration. The adjustment period is about three months. Usually after the initial dose, the spotting does stop and most women will either have no periods, or very light and short periods."
  • How long does it take for the shot to wear off?

    Broadly speaking each progesterone contraception injection (Depo-Provera) will last for 10 to 12 weeks, after which there is not enough contraceptive left at the injection site to definitely prevent a pregnancy.
  • How long do I have to wait after Depo shot?

    If you get your first Depo-Provera shot later than five days after your period, you will need to use condoms for the first seven days following the shot. If you want to continue to use Depo-Provera for birth control, you must return for another shot in 11 to 12 weeks, but no later than 13 weeks.
