Abortions happen early on in pregnancy 10-12 weeks, a fetus only develops pain 24-25 weeks

A fetus is essentially a parasite until the umbilical cord is cut, Merriam-Webster defines a parasite as "an organism living in, on, or with another organism in order to obtain nutrients, grow, or multiply often in a state that directly or indirectly harms the host." and fetus's do cause harm to the mother. IF the mother is raped, the condom broke, not enough money to support the baby or they just dont want one its their body.
