I have gestational diabetes controlled with diet and my numbers have been pretty awesome. My dr scheduled me for a sonogram at 34 weeks to check on baby’s growth and size. I pay for these out of pocket (~$200) and I’m wondering if this scan is even necessary. My measured fundal height has been about 2 weeks ahead for the past 6 weeks. I’ve heard that neither the fundal height or the sonograms are super reliable anyway and we are about to move and could use the money on baby things or needed furniture. Any thoughts?
