Ok so my girlfriend got depo provera (medroxyprogesterone) shot and she got it in july and we had unprotected sex on august 31 is there a chance of being pregnant ??

DepoProvera: DepoProvera is an effective form of birth control. When starting a new birth control treatment, we usually recommend using an additional form of contraception for the first month. However, it was almost 2 months since the shot, so the likelihood of pregnancy is low. Not all women menstruate while on the Depo shot, so she may want to take a pregnancy test in the next month.
