You cannot tell your girlfriend what kind of contraception she uses. There's no "line" in poly, the whole point is you and she develop your OWN rules.
However, this is something you DO have a personal choice. You can gently tell her that she has the right to do what she wishes with her body (she does!), but that if pregnancy does occur you will have nothing to do with raising the child, no financial help, no child care, and no help with abortion costs, if that's her choice.
If she chooses to engage in what you consider risky behavior, still, that is on her.
