Can I douche my girlfriend since she is passed out and I don't want her to get pregnant. Do I use tonic water?

or something else? I know not bleach like this one asshole told me to do. Should I suction it out too or will it just fall out. I don't want her to be pregnant and the condom came off inside her when I exploded in it so I'm really scared and she already passed out/went ot sleep without cleaning herself. I don't know what to doooooo!!!!!!!!!!! HELP ME!!!!!!!!!!!!!!! I'm to young and poor to become a father, especially because if I do, my own father will kick my azzzzzz.
