What are my chances of getting pregnant on deposit?

Conception: By deposit meaning intercourse, then the chances are approximately 15 to 20% per cycle.

On Depo Provera (medroxyprogesterone)?: You may be a victim of autocorrect. Depo-provera (a birth control shot) is very effective as long as you get shots at the right time and don't skip shots or get them later than your doctors office recommends. The chance of getting pregnant is less than 1 in 100 women in a year if you are on time getting the shots, maybe 3 in 100 women if you don't get the shots every 12 weeks.
