I been off the depo-provera shot for 6 months & tryin to get pregnant i hvnt had a period since i've been off the shot but i recently been spottin whts goin on?

Depo shot: Depoprovera can last a few months in the system after the last dose. It can take even up to 18 months to regain fertility after the last shot. Now that you are not using it, the body is regaining the tissues that lies inside the uterus and that could be the cause of your symptom. However always consider pregnancy if you are not using contraception.
