After nearly a year with a 15-week abortion ban in place, Florida appears poised to restrict it even further. In similar bills introduced in the two houses of the state Legislature last week, Republicans proposed banning nearly all abortions performed after six weeks of pregnancy. The GOP supermajorities that control the Florida House and Senate are expected to pass the bills easily, and Gov. Ron DeSantis has said he will sign the ban into law.

Perhaps some legislators in favor of the proposed ban know [that, in a state with a six-week abortion ban, a patient has about a weeklong opening in which to legally terminate a pregnancy]. It is likely that, for a good number of them, the dwindling likelihood that a Florida woman would be able to identify and terminate an unplanned pregnancy before her legal window slams shut is the entire point of the bill, because it will make her more likely to give up and give birth.

But surely, many of the ban’s supporters do not know—or particularly care—when the initial gestational sac of a pregnancy becomes visible on an ultrasound, or that “six weeks” pregnant typically means just four weeks after conception. They may not be aware that “six weeks” pregnant is only two weeks after the first indication of a missed period—in a person with a perfectly regular menstrual cycle.

These are medical details that pertain to pregnancy as a biological condition—a thing that happens to the body, explicable by science and the provenance of doctors—that is intimately entwined with health, pain, and injury. For all its clamoring about “heartbeats” and “fetal pain,” the anti-abortion right has no interest in the biological particulars of pregnancy.
