You're right about pregnancy categories, but you'll note that I'm talking about meds that will prevent implantation of a fertilized egg in the first place. As far as I can tell, the FDA hasn't been categorizing meds according to this possibility because it's impossible to detect, and nobody but pro-lifers and fertility doctors really cares.

And while pharmacists may sometimes be clued in to the purpose of birth control medication, that's far from universal. I take BCP entirely for medical reasons these days, and it's billed just the same as anyone else's birth control. Which means that if I ever got a pharmacist that thought I was ZOMG KILLING BABIES by taking it, I have no idea how I'd be able to convince them otherwise. I guess I could have my doctor call them, or carry around a note, but that's a serious hassle especially when my insurance won't let me get more than a month's worth at a time. Plus, the pharmacist could still think that my health problems aren't worth potentially killing babies for, and I don't know how to get around that. I don't really relish the idea of having to convince a stranger in public that I am not sexually active and, when I am sexually active, always use barrier contraception as backup.
