Can I get pregnant after taking Medroxyprogesterone?

My Dr. put me on Medroxyprogesterone to flush my uterin lining becuase it was too thick, so I took the pills and now I'm done bleeding so everything should be back in order. What I want to know is, is it possible to get pregnant after taking it? My last period after taking the meds was Nov. 8th, which means I should OV Nov. 21 or 22nd I think, and I've been doing the BD every night and plan on continuing to until at least Mon. So yea, my main question I guess is, can you get pregnant while taking it?
