I understand thought experiments. I just don’t think this one is useful for discussing invasive things like pregnancy and labor.
If the thought experiment was, what if someone has a gun to their head and says they’ll kill themselves (or a gun to someone else’s head and says they’ll kill them) unless you have sex with them, I would continue to agree that, like pregnancy, no, no one morally or legally needs to sacrifice their body autonomy in such an invasive way, even to save a life.
At the same time, a fertilized embryo is not a person.
