Does the right to bodily autonomy override the right to life?

It’s not enough to ask whether the unborn human has an objective right to life, just as a human being not located in a uterus has. We also need to consider whether a woman’s right to determine what she does with her body (specifically, whether she uses her body to support another human being) overrides the other human being’s right to life. It’s very difficult to find a thought experiment that mirrors the unique human condition that is pregnancy, but I have found one that seems to come close: that of conjoined twins.
