Hi. I'm a nursing student writing a short 'teaching topics' paper for my maternity rotation. MY topic is contraception. Anyway...how would you categorize an IUD? I suppose the Mirena would be categorized as hormonal (but non-systemic), but how do you categorize the Paragard? Would they even be categorized together (categorizing them together would work a lot better for me since I've already written up the explanation for the both together.
