I really don't understand what everyone here is practically suggesting. Do you want to question every woman who wants to abort her embryo?
First off, Fetus /=/ Embryo - they are two different terms referring to two different stages of pregnancy. This question specifically asked about fetuses, which refers to the 9th week of Pregnancy and beyond. Embryo is first 8 weeks only.
Second, with
any limitation on abortion comes some form of questioning. You want a parental notification requirement? Congratulations, you're asking the woman whether her parents know. You want to limit late term abortions to life or health of the mother? Congratulations, you're asking (either directly or indirectly through medical tools) whether the abortion is being done for a medical reason. You want a blanket ban on abortion after 24 weeks? Congratulations, you're asking (either directly or indirectly through medical tools) how long the woman has been pregnant. Unless you literally want free and unfettered abortion at any point in pregnancy, some form of questioning is required to enforce literally any limitation on abortion.
