Well, positive or negative results, congratulations! (either to the fact that you have just procreated, or else the fact that you get to procreate period)
Watch out for that shot though, it's narsty. Had a few close calls with it before. The pill + a condom is the way to go... redundant defense systems. Just like network administration.
And I think I should go jump off a bridge now since I just compared birth control to network security.
