749: Order of Events

Does anyone else ever get this? As someone who waited well into my 20's to make love, I feel like I'm constantly plagued by suspicious doctors who want to give me pregnancy tests because I don't remember the dates of my menstrual cycle. Why would I bother to keep track of that? I remember when I was 23 in China I literally chased a nurse out of the office and three a unused pee stick at her. I especially love that when I just told them point blank that it was impossible they acted like I was the one over sharing information or implying that they were asking a very personal question. How is asking a woman about her menses not personal?
