s a question that we throw around here alot, actually! I tend to think that the
charts,
graphs and reports are referring to natural conceptions, so from LMP - IVF makes it difficult because we know exactly when we conceived, unlike most women! I'd try to check websites that list values for IVF, maybe?
My mom said to me during my pregnancy, which I lost at 8 weeks, that I had the unfortunate situation of having too much knowledge!
