Hi Leasha *waves back*.. Our doctor does at least one blood test on day 11 or 12, and he measures the Estrogen (level should be about 500 per mature folllicle) and he measures the LH (to make sure there isnt a surge immenient) and it depends on those levels as to when we trigger. He also measures progestrone (should be low, kims was 2 on day 12). Clomid follicles grow much larger than natural or injectables, so he really does rely on the measurements PLUS the bloods. I would ask for blood monitoring as well, just to be on the safe side.
