Is it poasible to not get pregnant after the depo-provera shot wears off ?

Use other Forms: Depo lasts three months. After that you must choose from the many other forms of safe contraception. Talk it over with your doctor.

The basics: The contraception process whether by implant, depo or pill is based on preventing you from releasing eggs. No egg=no pregnancy. When the pill/implant/depo is gone, your body returns to its previous state. If you would have had fertility problems before you used contraception, they would exist after you stopped.
