No, it's not.
A parasite is an organism that is fully dependent upon another organism (from a different species most often) to live, and in the relationship between the two animals, one benefits and one is hurt.
A fetus is a stage of life in humans and other animals.
Parasites, after they are born, latch onto other animals to survive. Fetuses are developing inside an organism of the same species in order to be born.
