Well talk about throwing a person for a loop!

So I had my non stress test today, and a different doctor was on call and she wanted to talk to me about my sugars because they always ask my fasting, well apparently a pregnant woman fasting sugar should be below 90! Mine are low-mid 90s. No one ever told me this I'm going by regular diabetic standards I tell my doc every week what my fasting are he says that fine! Im So confused!!!! This doctor ordered me to have ultrasounds once a week to keep an eye on the babies weight since I have such large babies even when they are early now I'm all freaking out how is it that different doctors do such different things for the same person?! Sorry for the spazzy rant here I've just been obsessing with what I eat and what my sugars are to find out I'm not even doing it right!
