The bill amounts to a near total ban precisely because of how early it cuts off legal abortion. At that stage in a pregnancy, most women don’t yet know that they are pregnant. Even those who do sometimes can’t access abortion care that early, as providers often prefer to wait until eight or 10 weeks of gestation to perform abortions, for safety reasons. Before that stage, it is difficult to rule out the possibility of an ectopic pregnancy, an unviable condition that can be fatal.
The answer to an ectopic pregnancy is abortion. There is therefore no reason to wait until an ectopic pregnancy is detected in order to have an abortion. Or rather, if abortion has been decided upon there’s no reason to wait.
If what is meant is that a 6 week ban means that ectopic pregnancies cannot be dealt with then that’s just confusing writing from this Guardian columnist. But then what actually happens is “treatment for an ectopic pregnancy” and assuming that that really is what is done then even the Catholic Church is fine with that.
