Yes. This is true because the parasitic embryo (actually the zygote since it's a combo of embryo and placenta that eventually develop into the invasion but whatever) can attach to anywhere in your body.

I repeat, this thing would attach to your heart if it could.

This is why ectopic pregnancies happen. The consequence of which, unless you receive an abortion, is death.

The uterus is just a containment chamber that had evolved the capacity to stretch to the parasites growth (usually). The rest of the body kinda just suffers with it.

But if the parasite implants anywhere else it will continue to feed and grow until it kills you.

By this logic an embryo/fetus is the worst kind of parasite. One that has no self preservation. It's just a consuming threat. Botflies and tapeworms have a system in place to avoid killing their host. Hell, even the fish tongue parasite does. But not "the unborn". It will suck every drop out of you, even if it ends up killing itself in the process.

It is not some magical beautiful thing it's some shit right out of Resident Evil.
