No.
There are at least 10 scientific distinctions between a parasite and a fetus (bolds & italics added for easy perusal):
A parasite is an organism of one species that lives in or on an organism of another species and receives nourishment from the host.
Parasites are invasive organism that come from an outside or external source. A fetus comes from an inside or internal source (ie fertilized egg)
Parasites are generally harmful to the hosts, fetuses may make a pregnant woman experience adverse health effects, but not nearly to the same level that a parasite generally does.
A parasite makes direct contact with the host's living tissues. A fetus lives in the placenta, fed by the umbilical cord, both of which are fetal tissue (ie the cells come from the baby).
When a parasite invades a host, the host tissue will usually respond by encapsulating the parasite in order tocut it off from other surrounding tissue. In the case of a fetus, the mother’s tissue will create a lining tissue that connects, rather than cuts off contact with other tissues (placenta lining).
Parasites usually elicit a surge of antibodies as an immunological response. With the fetus, however, a mother’s trophoblast (the shell of cells surrounding the embryo) will naturally block these antibodies so as not to reject the fetus. This reaction is only found in the embryo-mother relationship.
A parasite will generally weaken the cellular reproductive capacity of the host.For a fetus, the effect is the opposite.
Parasites generally stay with the host for life, a fetus leaves upon birth.
Parasitical relationships are mostlyharmful and unnecessary to the host, generally damaging the host in a variety of ways. A newborn (fetus post-birth) is very healthy for the mother, bringing benefits of an emotional, cognitive and chemical nature.
The most obvious one, a fetus is a human being in development. It will never become anything other than human. Even a first trimester fetus will have fully developed arms, legs, ears, facial features, sex organs and a functioning heart, as well as sufficient neurological development to feel pain. A parasite is not a human and never will be.
