And the hits just keep on coming

Well, I failed my 3-hour glucose test--just barely, according to the nurse. So now I get to go spend two hours next Tuesday "learning" how to test my blood sugar (which I already know how to do--and teach others how to do), and meeting with a dietitian. I'm not sure how credible the information on the Internet is regarding accepted values for the tests because they change all the time, but according to one source, I DID just barely fail. I had to pass each blood draw; I missed the first one by just a point or two, but I made the other two. So, I don't think I have been officially diagnosed with Gestational Diabetes, but I definitely have impaired glucose tolerance. It shouldn't really surprise me given that I had been diagnosed with PCOS before I was pregnant (and who knows how long that went undiagnosed); it's still really disappointing. I feel like I must not have been taking good enough care of myself, and that's why I have to do all of this now, but I know intellectually that that's not the case. I have been trying to watch what I eat and how much, and I haven't gained any more weight than I should have. I know everyone's just being cautious, and it's always better to err on the side of caution, but I feel as though I have this big "Fail" label stamped on my forehead.
