Recently released are new health guidelines for women of reproductive age. The guidelines are a mix of basic good health (don't be obese) and preparation for pregnancy (take folic acid). Basically, women should always consider themselves pre-pregnant, since women need to be in good health to get pregnant. Theoretically. Also, since 50% of pregnancies are unplanned, the guidelines are aimed at keeping women perpetually ready for a healthy pregnancy.
Don't you think that women who are honestly going to take folic acid supplements regularly are the same ones who can take their birth control regularly and do a pretty good job of controlling their fertility? Plus, is it me, or is it a little weird to be "Forever Pregnant" as the WaPo article says.
Also also, apparently comprehensive sex ed does a decent job of educating kids, but not of changing their behavior. According to this study, information about EC increased the use, but EC is a post-coital contraceptive, unlike condoms or hormonal contraceptives.
