Question: how long does it take to get pregnant after leaving the injection?
Answer: You can become pregnant as soon as 3 to 4 months after your last shot, but it takes some women up to a year or 2 to conceive after they stop using this type of birth control. This time frame seems unrelated to how long you used the shot. SOURCES: FamilyDoctor.org: "Depo-Provera: An Injectable Contraceptive."
