Just wondering how to determine what "day 1" is...is it the day you set the eggs, or the next day? I may be over-thinking this, but I work in the medical field; infertility, to be exact. Calculation "day one" is very important for gathering information and calculation timing for procedures. "Day one" for us is the first day of "full flow" (sorry to be clinical). And when that starts is how we determine "day one." Is there a better or worse time for starting eggs? Thanks for your input!
