I think it says a lot about public attitudes toward reproductive health care that more people didn’t immediately notice that glaring plot hole.
If Anakin turned to the Dark Side because he had a premonition that Padme was going to die of an inflamed appendix then every theatergoer would immediately react with “What?? Are we seriously supposed to believe that’s a major risk in a society with advanced medical science?” But “dying in childbirth” seems like a totally legit fear and “total ignorance of a condition that should have been known from the very first prenatal checkup” doesn’t even get an explanation.
