On Nurx's website, women can choose which birth control they'd like or have a doctor pick one for them. Each woman answers a series of medical questions, such as "have you had your blood pressure measured in the last six months?" or "will you be skipping the placebo pills to avoid having periods?" If, for example, a woman hadn't had her blood pressure measured in the last six months, she would have to get it measured and then upload proof that the pressure is normal before moving on to the rest of the questionnaire.
